Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574092, here are decompositions:

71 + 31574021 = 31574092
131 + 31573961 = 31574092
233 + 31573859 = 31574092
239 + 31573853 = 31574092
269 + 31573823 = 31574092
449 + 31573643 = 31574092
509 + 31573583 = 31574092
521 + 31573571 = 31574092

Showing the first eight; more decompositions exist.
