Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474710, here are decompositions:

17 + 31474693 = 31474710
19 + 31474691 = 31474710
23 + 31474687 = 31474710
37 + 31474673 = 31474710
41 + 31474669 = 31474710
109 + 31474601 = 31474710
139 + 31474571 = 31474710
151 + 31474559 = 31474710

Showing the first eight; more decompositions exist.
