Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479692, here are decompositions:

43 + 31479649 = 31479692
73 + 31479619 = 31479692
103 + 31479589 = 31479692
151 + 31479541 = 31479692
193 + 31479499 = 31479692
271 + 31479421 = 31479692
421 + 31479271 = 31479692
619 + 31479073 = 31479692

Showing the first eight; more decompositions exist.
