Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493108, here are decompositions:

61 + 31493047 = 31493108
79 + 31493029 = 31493108
271 + 31492837 = 31493108
307 + 31492801 = 31493108
331 + 31492777 = 31493108
337 + 31492771 = 31493108
457 + 31492651 = 31493108
541 + 31492567 = 31493108

Showing the first eight; more decompositions exist.
