Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971830, here are decompositions:

  • 157 + 4294971673 = 4294971830
  • 223 + 4294971607 = 4294971830
  • 439 + 4294971391 = 4294971830
  • 463 + 4294971367 = 4294971830
  • 631 + 4294971199 = 4294971830
  • 661 + 4294971169 = 4294971830
  • 733 + 4294971097 = 4294971830
  • 757 + 4294971073 = 4294971830

Showing the first eight; more decompositions exist.
