Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479652, here are decompositions:

3 + 31479649 = 31479652
5 + 31479647 = 31479652
59 + 31479593 = 31479652
101 + 31479551 = 31479652
233 + 31479419 = 31479652
353 + 31479299 = 31479652
383 + 31479269 = 31479652
401 + 31479251 = 31479652

Showing the first eight; more decompositions exist.
