Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492776, here are decompositions:

5 + 31492771 = 31492776
19 + 31492757 = 31492776
79 + 31492697 = 31492776
109 + 31492667 = 31492776
113 + 31492663 = 31492776
149 + 31492627 = 31492776
173 + 31492603 = 31492776
179 + 31492597 = 31492776

Showing the first eight; more decompositions exist.
