Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479094, here are decompositions:

11 + 31479083 = 31479094
137 + 31478957 = 31479094
263 + 31478831 = 31479094
683 + 31478411 = 31479094
701 + 31478393 = 31479094
743 + 31478351 = 31479094
761 + 31478333 = 31479094
827 + 31478267 = 31479094

Showing the first eight; more decompositions exist.
