Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490932, here are decompositions:

113 + 31490819 = 31490932
191 + 31490741 = 31490932
281 + 31490651 = 31490932
311 + 31490621 = 31490932
359 + 31490573 = 31490932
443 + 31490489 = 31490932
479 + 31490453 = 31490932
563 + 31490369 = 31490932

Showing the first eight; more decompositions exist.
