Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607084, here are decompositions:

37 + 31607047 = 31607084
127 + 31606957 = 31607084
181 + 31606903 = 31607084
331 + 31606753 = 31607084
373 + 31606711 = 31607084
433 + 31606651 = 31607084
541 + 31606543 = 31607084
547 + 31606537 = 31607084

Showing the first eight; more decompositions exist.
