Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471526, here are decompositions:

3 + 31471523 = 31471526
139 + 31471387 = 31471526
313 + 31471213 = 31471526
379 + 31471147 = 31471526
433 + 31471093 = 31471526
613 + 31470913 = 31471526
673 + 31470853 = 31471526
727 + 31470799 = 31471526

Showing the first eight; more decompositions exist.
