Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492976, here are decompositions:

13 + 31492963 = 31492976
43 + 31492933 = 31492976
127 + 31492849 = 31492976
139 + 31492837 = 31492976
199 + 31492777 = 31492976
313 + 31492663 = 31492976
349 + 31492627 = 31492976
373 + 31492603 = 31492976

Showing the first eight; more decompositions exist.
