Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499396, here are decompositions:

13 + 31499383 = 31499396
67 + 31499329 = 31499396
73 + 31499323 = 31499396
157 + 31499239 = 31499396
373 + 31499023 = 31499396
433 + 31498963 = 31499396
499 + 31498897 = 31499396
547 + 31498849 = 31499396

Showing the first eight; more decompositions exist.
