Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522846, here are decompositions:

23 + 31522823 = 31522846
233 + 31522613 = 31522846
263 + 31522583 = 31522846
293 + 31522553 = 31522846
317 + 31522529 = 31522846
353 + 31522493 = 31522846
569 + 31522277 = 31522846
599 + 31522247 = 31522846

Showing the first eight; more decompositions exist.
