Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497794, here are decompositions:

37 + 31497757 = 31497794
43 + 31497751 = 31497794
67 + 31497727 = 31497794
73 + 31497721 = 31497794
127 + 31497667 = 31497794
157 + 31497637 = 31497794
193 + 31497601 = 31497794
271 + 31497523 = 31497794

Showing the first eight; more decompositions exist.
