Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529396, here are decompositions:

37 + 31529359 = 31529396
43 + 31529353 = 31529396
127 + 31529269 = 31529396
139 + 31529257 = 31529396
229 + 31529167 = 31529396
307 + 31529089 = 31529396
487 + 31528909 = 31529396
673 + 31528723 = 31529396

Showing the first eight; more decompositions exist.
