Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616798, here are decompositions:

127 + 31616671 = 31616798
151 + 31616647 = 31616798
229 + 31616569 = 31616798
277 + 31616521 = 31616798
379 + 31616419 = 31616798
397 + 31616401 = 31616798
439 + 31616359 = 31616798
541 + 31616257 = 31616798

Showing the first eight; more decompositions exist.
