Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479576, here are decompositions:

17 + 31479559 = 31479576
19 + 31479557 = 31479576
59 + 31479517 = 31479576
109 + 31479467 = 31479576
137 + 31479439 = 31479576
157 + 31479419 = 31479576
239 + 31479337 = 31479576
269 + 31479307 = 31479576

Showing the first eight; more decompositions exist.
