Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465832, here are decompositions:

3 + 31465829 = 31465832
31 + 31465801 = 31465832
43 + 31465789 = 31465832
271 + 31465561 = 31465832
373 + 31465459 = 31465832
523 + 31465309 = 31465832
709 + 31465123 = 31465832
733 + 31465099 = 31465832

Showing the first eight; more decompositions exist.
