Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499934, here are decompositions:

13 + 31499921 = 31499934
41 + 31499893 = 31499934
71 + 31499863 = 31499934
101 + 31499833 = 31499934
131 + 31499803 = 31499934
173 + 31499761 = 31499934
223 + 31499711 = 31499934
313 + 31499621 = 31499934

Showing the first eight; more decompositions exist.
