Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632780, here are decompositions:

  • 3 + 8632777 = 8632780
  • 53 + 8632727 = 8632780
  • 113 + 8632667 = 8632780
  • 131 + 8632649 = 8632780
  • 251 + 8632529 = 8632780
  • 257 + 8632523 = 8632780
  • 293 + 8632487 = 8632780
  • 389 + 8632391 = 8632780

Showing the first eight; more decompositions exist.
