Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463130, here are decompositions:

7 + 31463123 = 31463130
31 + 31463099 = 31463130
43 + 31463087 = 31463130
47 + 31463083 = 31463130
53 + 31463077 = 31463130
67 + 31463063 = 31463130
107 + 31463023 = 31463130
151 + 31462979 = 31463130

Showing the first eight; more decompositions exist.
