Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476786, here are decompositions:

43 + 31476743 = 31476786
53 + 31476733 = 31476786
59 + 31476727 = 31476786
83 + 31476703 = 31476786
163 + 31476623 = 31476786
179 + 31476607 = 31476786
193 + 31476593 = 31476786
199 + 31476587 = 31476786

Showing the first eight; more decompositions exist.
