Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493036, here are decompositions:

7 + 31493029 = 31493036
19 + 31493017 = 31493036
73 + 31492963 = 31493036
103 + 31492933 = 31493036
199 + 31492837 = 31493036
373 + 31492663 = 31493036
409 + 31492627 = 31493036
433 + 31492603 = 31493036

Showing the first eight; more decompositions exist.
