Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463230, here are decompositions:

3 + 31463227 = 31463230
17 + 31463213 = 31463230
83 + 31463147 = 31463230
107 + 31463123 = 31463230
131 + 31463099 = 31463230
167 + 31463063 = 31463230
251 + 31462979 = 31463230
353 + 31462877 = 31463230

Showing the first eight; more decompositions exist.
