Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476608, here are decompositions:

61 + 31476547 = 31476608
109 + 31476499 = 31476608
151 + 31476457 = 31476608
157 + 31476451 = 31476608
421 + 31476187 = 31476608
439 + 31476169 = 31476608
577 + 31476031 = 31476608
811 + 31475797 = 31476608

Showing the first eight; more decompositions exist.
