Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557362, here are decompositions:

19 + 31557343 = 31557362
79 + 31557283 = 31557362
163 + 31557199 = 31557362
223 + 31557139 = 31557362
241 + 31557121 = 31557362
349 + 31557013 = 31557362
439 + 31556923 = 31557362
709 + 31556653 = 31557362

Showing the first eight; more decompositions exist.
