Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471796, here are decompositions:

157 + 31471639 = 31471796
163 + 31471633 = 31471796
409 + 31471387 = 31471796
439 + 31471357 = 31471796
673 + 31471123 = 31471796
883 + 31470913 = 31471796
907 + 31470889 = 31471796
997 + 31470799 = 31471796

Showing the first eight; more decompositions exist.
