Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465532, here are decompositions:

3 + 31465529 = 31465532
73 + 31465459 = 31465532
211 + 31465321 = 31465532
223 + 31465309 = 31465532
349 + 31465183 = 31465532
379 + 31465153 = 31465532
409 + 31465123 = 31465532
421 + 31465111 = 31465532

Showing the first eight; more decompositions exist.
