Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471496, here are decompositions:

109 + 31471387 = 31471496
139 + 31471357 = 31471496
283 + 31471213 = 31471496
349 + 31471147 = 31471496
373 + 31471123 = 31471496
499 + 31470997 = 31471496
607 + 31470889 = 31471496
643 + 31470853 = 31471496

Showing the first eight; more decompositions exist.
