Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519496, here are decompositions:

13 + 31519483 = 31519496
37 + 31519459 = 31519496
79 + 31519417 = 31519496
139 + 31519357 = 31519496
199 + 31519297 = 31519496
397 + 31519099 = 31519496
439 + 31519057 = 31519496
739 + 31518757 = 31519496

Showing the first eight; more decompositions exist.
