Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519514, here are decompositions:

7 + 31519507 = 31519514
31 + 31519483 = 31519514
73 + 31519441 = 31519514
97 + 31519417 = 31519514
151 + 31519363 = 31519514
157 + 31519357 = 31519514
193 + 31519321 = 31519514
373 + 31519141 = 31519514

Showing the first eight; more decompositions exist.
