Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476762, here are decompositions:

19 + 31476743 = 31476762
29 + 31476733 = 31476762
59 + 31476703 = 31476762
71 + 31476691 = 31476762
131 + 31476631 = 31476762
139 + 31476623 = 31476762
151 + 31476611 = 31476762
211 + 31476551 = 31476762

Showing the first eight; more decompositions exist.
