Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479594, here are decompositions:

5 + 31479589 = 31479594
17 + 31479577 = 31479594
37 + 31479557 = 31479594
43 + 31479551 = 31479594
53 + 31479541 = 31479594
103 + 31479491 = 31479594
127 + 31479467 = 31479594
137 + 31479457 = 31479594

Showing the first eight; more decompositions exist.
