Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514450, here are decompositions:

31 + 31514419 = 31514450
211 + 31514239 = 31514450
229 + 31514221 = 31514450
307 + 31514143 = 31514450
337 + 31514113 = 31514450
349 + 31514101 = 31514450
463 + 31513987 = 31514450
523 + 31513927 = 31514450

Showing the first eight; more decompositions exist.
