Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487336, here are decompositions:

7 + 31487329 = 31487336
19 + 31487317 = 31487336
73 + 31487263 = 31487336
103 + 31487233 = 31487336
193 + 31487143 = 31487336
337 + 31486999 = 31487336
409 + 31486927 = 31487336
613 + 31486723 = 31487336

Showing the first eight; more decompositions exist.
