Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479046, here are decompositions:

29 + 31479017 = 31479046
89 + 31478957 = 31479046
113 + 31478933 = 31479046
239 + 31478807 = 31479046
479 + 31478567 = 31479046
563 + 31478483 = 31479046
617 + 31478429 = 31479046
647 + 31478399 = 31479046

Showing the first eight; more decompositions exist.
