Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541728, here are decompositions:

  • 131 + 31541597 = 31541728
  • 137 + 31541591 = 31541728
  • 311 + 31541417 = 31541728
  • 431 + 31541297 = 31541728
  • 461 + 31541267 = 31541728
  • 587 + 31541141 = 31541728
  • 599 + 31541129 = 31541728
  • 677 + 31541051 = 31541728

Showing the first eight; more decompositions exist.
