Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522336, here are decompositions:

5 + 31522331 = 31522336
23 + 31522313 = 31522336
59 + 31522277 = 31522336
89 + 31522247 = 31522336
107 + 31522229 = 31522336
233 + 31522103 = 31522336
317 + 31522019 = 31522336
359 + 31521977 = 31522336

Showing the first eight; more decompositions exist.
