Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519304, here are decompositions:

7 + 31519297 = 31519304
163 + 31519141 = 31519304
547 + 31518757 = 31519304
613 + 31518691 = 31519304
631 + 31518673 = 31519304
823 + 31518481 = 31519304
853 + 31518451 = 31519304
877 + 31518427 = 31519304

Showing the first eight; more decompositions exist.
