Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479610, here are decompositions:

17 + 31479593 = 31479610
53 + 31479557 = 31479610
59 + 31479551 = 31479610
191 + 31479419 = 31479610
311 + 31479299 = 31479610
359 + 31479251 = 31479610
479 + 31479131 = 31479610
509 + 31479101 = 31479610

Showing the first eight; more decompositions exist.
