Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523692, here are decompositions:

23 + 31523669 = 31523692
41 + 31523651 = 31523692
59 + 31523633 = 31523692
113 + 31523579 = 31523692
251 + 31523441 = 31523692
281 + 31523411 = 31523692
293 + 31523399 = 31523692
311 + 31523381 = 31523692

Showing the first eight; more decompositions exist.
