Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465382, here are decompositions:

19 + 31465363 = 31465382
61 + 31465321 = 31465382
73 + 31465309 = 31465382
139 + 31465243 = 31465382
199 + 31465183 = 31465382
229 + 31465153 = 31465382
271 + 31465111 = 31465382
283 + 31465099 = 31465382

Showing the first eight; more decompositions exist.
