Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519076, here are decompositions:

3 + 31519073 = 31519076
7 + 31519069 = 31519076
19 + 31519057 = 31519076
163 + 31518913 = 31519076
283 + 31518793 = 31519076
487 + 31518589 = 31519076
619 + 31518457 = 31519076
733 + 31518343 = 31519076

Showing the first eight; more decompositions exist.
