Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541350, here are decompositions:

  • 3 + 31541347 = 31541350
  • 53 + 31541297 = 31541350
  • 83 + 31541267 = 31541350
  • 107 + 31541243 = 31541350
  • 233 + 31541117 = 31541350
  • 311 + 31541039 = 31541350
  • 359 + 31540991 = 31541350
  • 389 + 31540961 = 31541350

Showing the first eight; more decompositions exist.
