Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522388, here are decompositions:

31 + 31522357 = 31522388
61 + 31522327 = 31522388
181 + 31522207 = 31522388
367 + 31522021 = 31522388
397 + 31521991 = 31522388
409 + 31521979 = 31522388
739 + 31521649 = 31522388
829 + 31521559 = 31522388

Showing the first eight; more decompositions exist.
