Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479314, here are decompositions:

7 + 31479307 = 31479314
37 + 31479277 = 31479314
43 + 31479271 = 31479314
73 + 31479241 = 31479314
241 + 31479073 = 31479314
283 + 31479031 = 31479314
313 + 31479001 = 31479314
331 + 31478983 = 31479314

Showing the first eight; more decompositions exist.
