Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619404, here are decompositions:

17 + 31619387 = 31619404
137 + 31619267 = 31619404
191 + 31619213 = 31619404
197 + 31619207 = 31619404
227 + 31619177 = 31619404
233 + 31619171 = 31619404
281 + 31619123 = 31619404
461 + 31618943 = 31619404

Showing the first eight; more decompositions exist.
