Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498596, here are decompositions:

5 + 31498591 = 31498596
37 + 31498559 = 31498596
47 + 31498549 = 31498596
67 + 31498529 = 31498596
79 + 31498517 = 31498596
83 + 31498513 = 31498596
97 + 31498499 = 31498596
127 + 31498469 = 31498596

Showing the first eight; more decompositions exist.
