Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616792, here are decompositions:

19 + 31616773 = 31616792
43 + 31616749 = 31616792
223 + 31616569 = 31616792
271 + 31616521 = 31616792
283 + 31616509 = 31616792
313 + 31616479 = 31616792
373 + 31616419 = 31616792
433 + 31616359 = 31616792

Showing the first eight; more decompositions exist.
