Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463190, here are decompositions:

23 + 31463167 = 31463190
29 + 31463161 = 31463190
43 + 31463147 = 31463190
53 + 31463137 = 31463190
67 + 31463123 = 31463190
103 + 31463087 = 31463190
107 + 31463083 = 31463190
113 + 31463077 = 31463190

Showing the first eight; more decompositions exist.
