Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486346, here are decompositions:

7 + 31486339 = 31486346
19 + 31486327 = 31486346
43 + 31486303 = 31486346
79 + 31486267 = 31486346
223 + 31486123 = 31486346
313 + 31486033 = 31486346
337 + 31486009 = 31486346
373 + 31485973 = 31486346

Showing the first eight; more decompositions exist.
