Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465346, here are decompositions:

37 + 31465309 = 31465346
103 + 31465243 = 31465346
163 + 31465183 = 31465346
193 + 31465153 = 31465346
223 + 31465123 = 31465346
277 + 31465069 = 31465346
307 + 31465039 = 31465346
313 + 31465033 = 31465346

Showing the first eight; more decompositions exist.
