Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479614, here are decompositions:

37 + 31479577 = 31479614
73 + 31479541 = 31479614
97 + 31479517 = 31479614
157 + 31479457 = 31479614
193 + 31479421 = 31479614
277 + 31479337 = 31479614
307 + 31479307 = 31479614
337 + 31479277 = 31479614

Showing the first eight; more decompositions exist.
