Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476720, here are decompositions:

17 + 31476703 = 31476720
29 + 31476691 = 31476720
89 + 31476631 = 31476720
97 + 31476623 = 31476720
109 + 31476611 = 31476720
113 + 31476607 = 31476720
127 + 31476593 = 31476720
173 + 31476547 = 31476720

Showing the first eight; more decompositions exist.
