Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492436, here are decompositions:

7 + 31492429 = 31492436
13 + 31492423 = 31492436
37 + 31492399 = 31492436
43 + 31492393 = 31492436
67 + 31492369 = 31492436
193 + 31492243 = 31492436
223 + 31492213 = 31492436
523 + 31491913 = 31492436

Showing the first eight; more decompositions exist.
