Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479604, here are decompositions:

11 + 31479593 = 31479604
47 + 31479557 = 31479604
53 + 31479551 = 31479604
113 + 31479491 = 31479604
137 + 31479467 = 31479604
353 + 31479251 = 31479604
503 + 31479101 = 31479604
521 + 31479083 = 31479604

Showing the first eight; more decompositions exist.
