Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533494, here are decompositions:

43 + 31533451 = 31533494
151 + 31533343 = 31533494
367 + 31533127 = 31533494
397 + 31533097 = 31533494
523 + 31532971 = 31533494
571 + 31532923 = 31533494
613 + 31532881 = 31533494
631 + 31532863 = 31533494

Showing the first eight; more decompositions exist.

IPv4 address
