Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530050, here are decompositions:

7 + 31530043 = 31530050
73 + 31529977 = 31530050
127 + 31529923 = 31530050
151 + 31529899 = 31530050
373 + 31529677 = 31530050
379 + 31529671 = 31530050
421 + 31529629 = 31530050
457 + 31529593 = 31530050

Showing the first eight; more decompositions exist.
