Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460796, here are decompositions:

5 + 31460791 = 31460796
13 + 31460783 = 31460796
53 + 31460743 = 31460796
67 + 31460729 = 31460796
79 + 31460717 = 31460796
139 + 31460657 = 31460796
149 + 31460647 = 31460796
313 + 31460483 = 31460796

Showing the first eight; more decompositions exist.
