Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522592, here are decompositions:

43 + 31522549 = 31522592
151 + 31522441 = 31522592
181 + 31522411 = 31522592
229 + 31522363 = 31522592
349 + 31522243 = 31522592
373 + 31522219 = 31522592
463 + 31522129 = 31522592
571 + 31522021 = 31522592

Showing the first eight; more decompositions exist.
