Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541010, here are decompositions:

  • 19 + 31540991 = 31541010
  • 31 + 31540979 = 31541010
  • 71 + 31540939 = 31541010
  • 89 + 31540921 = 31541010
  • 139 + 31540871 = 31541010
  • 173 + 31540837 = 31541010
  • 197 + 31540813 = 31541010
  • 223 + 31540787 = 31541010

Showing the first eight; more decompositions exist.

IPv4 address
