Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550524, here are decompositions:

53 + 31550471 = 31550524
167 + 31550357 = 31550524
197 + 31550327 = 31550524
311 + 31550213 = 31550524
347 + 31550177 = 31550524
431 + 31550093 = 31550524
461 + 31550063 = 31550524
503 + 31550021 = 31550524

Showing the first eight; more decompositions exist.
