Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463452, here are decompositions:

23 + 31463429 = 31463452
89 + 31463363 = 31463452
131 + 31463321 = 31463452
191 + 31463261 = 31463452
239 + 31463213 = 31463452
353 + 31463099 = 31463452
389 + 31463063 = 31463452
521 + 31462931 = 31463452

Showing the first eight; more decompositions exist.
