Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463196, here are decompositions:

29 + 31463167 = 31463196
59 + 31463137 = 31463196
73 + 31463123 = 31463196
97 + 31463099 = 31463196
109 + 31463087 = 31463196
113 + 31463083 = 31463196
173 + 31463023 = 31463196
227 + 31462969 = 31463196

Showing the first eight; more decompositions exist.
