Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479034, here are decompositions:

3 + 31479031 = 31479034
17 + 31479017 = 31479034
101 + 31478933 = 31479034
227 + 31478807 = 31479034
467 + 31478567 = 31479034
563 + 31478471 = 31479034
641 + 31478393 = 31479034
683 + 31478351 = 31479034

Showing the first eight; more decompositions exist.
