Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446792, here are decompositions:

23 + 31446769 = 31446792
31 + 31446761 = 31446792
43 + 31446749 = 31446792
53 + 31446739 = 31446792
103 + 31446689 = 31446792
151 + 31446641 = 31446792
199 + 31446593 = 31446792
229 + 31446563 = 31446792

Showing the first eight; more decompositions exist.
