Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530524, here are decompositions:

37 + 31530487 = 31530524
73 + 31530451 = 31530524
313 + 31530211 = 31530524
463 + 31530061 = 31530524
523 + 31530001 = 31530524
547 + 31529977 = 31530524
601 + 31529923 = 31530524
643 + 31529881 = 31530524

Showing the first eight; more decompositions exist.
