Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616044, here are decompositions:

3 + 31616041 = 31616044
11 + 31616033 = 31616044
23 + 31616021 = 31616044
71 + 31615973 = 31616044
197 + 31615847 = 31616044
281 + 31615763 = 31616044
461 + 31615583 = 31616044
641 + 31615403 = 31616044

Showing the first eight; more decompositions exist.
