Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479962, here are decompositions:

13 + 31479949 = 31479962
193 + 31479769 = 31479962
223 + 31479739 = 31479962
313 + 31479649 = 31479962
373 + 31479589 = 31479962
421 + 31479541 = 31479962
463 + 31479499 = 31479962
523 + 31479439 = 31479962

Showing the first eight; more decompositions exist.
