Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494236, here are decompositions:

79 + 31494157 = 31494236
139 + 31494097 = 31494236
157 + 31494079 = 31494236
337 + 31493899 = 31494236
379 + 31493857 = 31494236
457 + 31493779 = 31494236
547 + 31493689 = 31494236
643 + 31493593 = 31494236

Showing the first eight; more decompositions exist.
