Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550536, here are decompositions:

5 + 31550531 = 31550536
89 + 31550447 = 31550536
179 + 31550357 = 31550536
197 + 31550339 = 31550536
359 + 31550177 = 31550536
383 + 31550153 = 31550536
443 + 31550093 = 31550536
509 + 31550027 = 31550536

Showing the first eight; more decompositions exist.
