Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479592, here are decompositions:

3 + 31479589 = 31479592
41 + 31479551 = 31479592
101 + 31479491 = 31479592
173 + 31479419 = 31479592
293 + 31479299 = 31479592
461 + 31479131 = 31479592
491 + 31479101 = 31479592
509 + 31479083 = 31479592

Showing the first eight; more decompositions exist.
