Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479974, here are decompositions:

13 + 31479961 = 31479974
157 + 31479817 = 31479974
181 + 31479793 = 31479974
277 + 31479697 = 31479974
397 + 31479577 = 31479974
433 + 31479541 = 31479974
457 + 31479517 = 31479974
733 + 31479241 = 31479974

Showing the first eight; more decompositions exist.
