Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470674, here are decompositions:

13 + 31470661 = 31470674
127 + 31470547 = 31470674
337 + 31470337 = 31470674
457 + 31470217 = 31470674
523 + 31470151 = 31470674
577 + 31470097 = 31470674
601 + 31470073 = 31470674
607 + 31470067 = 31470674

Showing the first eight; more decompositions exist.
