Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499846, here are decompositions:

3 + 31499843 = 31499846
13 + 31499833 = 31499846
43 + 31499803 = 31499846
349 + 31499497 = 31499846
379 + 31499467 = 31499846
439 + 31499407 = 31499846
463 + 31499383 = 31499846
523 + 31499323 = 31499846

Showing the first eight; more decompositions exist.
