Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535942, here are decompositions:

3 + 31535939 = 31535942
271 + 31535671 = 31535942
349 + 31535593 = 31535942
439 + 31535503 = 31535942
523 + 31535419 = 31535942
601 + 31535341 = 31535942
631 + 31535311 = 31535942
709 + 31535233 = 31535942

Showing the first eight; more decompositions exist.

IPv4 address
