Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574792, here are decompositions:

13 + 31574779 = 31574792
19 + 31574773 = 31574792
103 + 31574689 = 31574792
229 + 31574563 = 31574792
313 + 31574479 = 31574792
349 + 31574443 = 31574792
373 + 31574419 = 31574792
463 + 31574329 = 31574792

Showing the first eight; more decompositions exist.
