Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465502, here are decompositions:

43 + 31465459 = 31465502
139 + 31465363 = 31465502
181 + 31465321 = 31465502
193 + 31465309 = 31465502
349 + 31465153 = 31465502
373 + 31465129 = 31465502
379 + 31465123 = 31465502
433 + 31465069 = 31465502

Showing the first eight; more decompositions exist.
