Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499744, here are decompositions:

13 + 31499731 = 31499744
151 + 31499593 = 31499744
277 + 31499467 = 31499744
313 + 31499431 = 31499744
337 + 31499407 = 31499744
373 + 31499371 = 31499744
421 + 31499323 = 31499744
433 + 31499311 = 31499744

Showing the first eight; more decompositions exist.
