Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510532, here are decompositions:

43 + 31510489 = 31510532
73 + 31510459 = 31510532
211 + 31510321 = 31510532
223 + 31510309 = 31510532
421 + 31510111 = 31510532
439 + 31510093 = 31510532
523 + 31510009 = 31510532
541 + 31509991 = 31510532

Showing the first eight; more decompositions exist.
