Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525226, here are decompositions:

13 + 31525213 = 31525226
43 + 31525183 = 31525226
199 + 31525027 = 31525226
433 + 31524793 = 31525226
463 + 31524763 = 31525226
619 + 31524607 = 31525226
709 + 31524517 = 31525226
727 + 31524499 = 31525226

Showing the first eight; more decompositions exist.
