Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476308, here are decompositions:

139 + 31476169 = 31476308
151 + 31476157 = 31476308
211 + 31476097 = 31476308
277 + 31476031 = 31476308
379 + 31475929 = 31476308
397 + 31475911 = 31476308
631 + 31475677 = 31476308
709 + 31475599 = 31476308

Showing the first eight; more decompositions exist.
