Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465412, here are decompositions:

103 + 31465309 = 31465412
229 + 31465183 = 31465412
283 + 31465129 = 31465412
313 + 31465099 = 31465412
373 + 31465039 = 31465412
379 + 31465033 = 31465412
409 + 31465003 = 31465412
421 + 31464991 = 31465412

Showing the first eight; more decompositions exist.
