Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522744, here are decompositions:

131 + 31522613 = 31522744
191 + 31522553 = 31522744
251 + 31522493 = 31522744
293 + 31522451 = 31522744
311 + 31522433 = 31522744
431 + 31522313 = 31522744
467 + 31522277 = 31522744
503 + 31522241 = 31522744

Showing the first eight; more decompositions exist.
