Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471256, here are decompositions:

43 + 31471213 = 31471256
109 + 31471147 = 31471256
163 + 31471093 = 31471256
367 + 31470889 = 31471256
409 + 31470847 = 31471256
433 + 31470823 = 31471256
457 + 31470799 = 31471256
463 + 31470793 = 31471256

Showing the first eight; more decompositions exist.
