Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492964, here are decompositions:

31 + 31492933 = 31492964
43 + 31492921 = 31492964
127 + 31492837 = 31492964
163 + 31492801 = 31492964
193 + 31492771 = 31492964
313 + 31492651 = 31492964
337 + 31492627 = 31492964
367 + 31492597 = 31492964

Showing the first eight; more decompositions exist.
