Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530134, here are decompositions:

37 + 31530097 = 31530134
73 + 31530061 = 31530134
157 + 31529977 = 31530134
211 + 31529923 = 31530134
457 + 31529677 = 31530134
463 + 31529671 = 31530134
541 + 31529593 = 31530134
577 + 31529557 = 31530134

Showing the first eight; more decompositions exist.
