Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522048, here are decompositions:

29 + 31522019 = 31522048
71 + 31521977 = 31522048
197 + 31521851 = 31522048
401 + 31521647 = 31522048
449 + 31521599 = 31522048
599 + 31521449 = 31522048
809 + 31521239 = 31522048
821 + 31521227 = 31522048

Showing the first eight; more decompositions exist.
