Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522804, here are decompositions:

191 + 31522613 = 31522804
251 + 31522553 = 31522804
263 + 31522541 = 31522804
281 + 31522523 = 31522804
311 + 31522493 = 31522804
353 + 31522451 = 31522804
431 + 31522373 = 31522804
491 + 31522313 = 31522804

Showing the first eight; more decompositions exist.
