Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542396, here are decompositions:

5 + 31542391 = 31542396
19 + 31542377 = 31542396
23 + 31542373 = 31542396
37 + 31542359 = 31542396
73 + 31542323 = 31542396
163 + 31542233 = 31542396
167 + 31542229 = 31542396
199 + 31542197 = 31542396

Showing the first eight; more decompositions exist.
