Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541494, here are decompositions:

  • 11 + 31541483 = 31541494
  • 197 + 31541297 = 31541494
  • 227 + 31541267 = 31541494
  • 251 + 31541243 = 31541494
  • 353 + 31541141 = 31541494
  • 443 + 31541051 = 31541494
  • 503 + 31540991 = 31541494
  • 857 + 31540637 = 31541494

Showing the first eight; more decompositions exist.
