Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616098, here are decompositions:

29 + 31616069 = 31616098
89 + 31616009 = 31616098
179 + 31615919 = 31616098
251 + 31615847 = 31616098
509 + 31615589 = 31616098
659 + 31615439 = 31616098
881 + 31615217 = 31616098
887 + 31615211 = 31616098

Showing the first eight; more decompositions exist.
