Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616234, here are decompositions:

3 + 31616231 = 31616234
61 + 31616173 = 31616234
193 + 31616041 = 31616234
211 + 31616023 = 31616234
241 + 31615993 = 31616234
283 + 31615951 = 31616234
313 + 31615921 = 31616234
523 + 31615711 = 31616234

Showing the first eight; more decompositions exist.
