Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616744, here are decompositions:

37 + 31616707 = 31616744
67 + 31616677 = 31616744
73 + 31616671 = 31616744
97 + 31616647 = 31616744
223 + 31616521 = 31616744
457 + 31616287 = 31616744
463 + 31616281 = 31616744
487 + 31616257 = 31616744

Showing the first eight; more decompositions exist.
