Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465482, here are decompositions:

23 + 31465459 = 31465482
31 + 31465451 = 31465482
173 + 31465309 = 31465482
193 + 31465289 = 31465482
239 + 31465243 = 31465482
353 + 31465129 = 31465482
359 + 31465123 = 31465482
383 + 31465099 = 31465482

Showing the first eight; more decompositions exist.
