Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529492, here are decompositions:

13 + 31529479 = 31529492
61 + 31529431 = 31529492
79 + 31529413 = 31529492
139 + 31529353 = 31529492
223 + 31529269 = 31529492
439 + 31529053 = 31529492
499 + 31528993 = 31529492
523 + 31528969 = 31529492

Showing the first eight; more decompositions exist.
