Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487366, here are decompositions:

3 + 31487363 = 31487366
19 + 31487347 = 31487366
37 + 31487329 = 31487366
103 + 31487263 = 31487366
223 + 31487143 = 31487366
367 + 31486999 = 31487366
439 + 31486927 = 31487366
643 + 31486723 = 31487366

Showing the first eight; more decompositions exist.
