Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465564, here are decompositions:

3 + 31465561 = 31465564
17 + 31465547 = 31465564
83 + 31465481 = 31465564
113 + 31465451 = 31465564
173 + 31465391 = 31465564
503 + 31465061 = 31465564
617 + 31464947 = 31465564
743 + 31464821 = 31465564

Showing the first eight; more decompositions exist.
