Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615698, here are decompositions:

29 + 31615669 = 31615698
47 + 31615651 = 31615698
89 + 31615609 = 31615698
109 + 31615589 = 31615698
227 + 31615471 = 31615698
269 + 31615429 = 31615698
281 + 31615417 = 31615698
307 + 31615391 = 31615698

Showing the first eight; more decompositions exist.
