Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479566, here are decompositions:

7 + 31479559 = 31479566
67 + 31479499 = 31479566
109 + 31479457 = 31479566
127 + 31479439 = 31479566
229 + 31479337 = 31479566
277 + 31479289 = 31479566
439 + 31479127 = 31479566
607 + 31478959 = 31479566

Showing the first eight; more decompositions exist.
