Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463370, here are decompositions:

7 + 31463363 = 31463370
17 + 31463353 = 31463370
41 + 31463329 = 31463370
53 + 31463317 = 31463370
89 + 31463281 = 31463370
101 + 31463269 = 31463370
109 + 31463261 = 31463370
157 + 31463213 = 31463370

Showing the first eight; more decompositions exist.
