Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492974, here are decompositions:

11 + 31492963 = 31492974
31 + 31492943 = 31492974
41 + 31492933 = 31492974
53 + 31492921 = 31492974
67 + 31492907 = 31492974
127 + 31492847 = 31492974
137 + 31492837 = 31492974
173 + 31492801 = 31492974

Showing the first eight; more decompositions exist.
