Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533038, here are decompositions:

37 + 31533001 = 31533038
67 + 31532971 = 31533038
79 + 31532959 = 31533038
139 + 31532899 = 31533038
157 + 31532881 = 31533038
379 + 31532659 = 31533038
457 + 31532581 = 31533038
487 + 31532551 = 31533038

Showing the first eight; more decompositions exist.

IPv4 address
