Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519364, here are decompositions:

7 + 31519357 = 31519364
43 + 31519321 = 31519364
67 + 31519297 = 31519364
223 + 31519141 = 31519364
307 + 31519057 = 31519364
571 + 31518793 = 31519364
607 + 31518757 = 31519364
673 + 31518691 = 31519364

Showing the first eight; more decompositions exist.
