Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615226, here are decompositions:

  • 73 + 31615153 = 31615226
  • 163 + 31615063 = 31615226
  • 283 + 31614943 = 31615226
  • 337 + 31614889 = 31615226
  • 367 + 31614859 = 31615226
  • 373 + 31614853 = 31615226
  • 397 + 31614829 = 31615226
  • 439 + 31614787 = 31615226

Showing the first eight; more decompositions exist.
