Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627350, here are decompositions:

17 + 31627333 = 31627350
31 + 31627319 = 31627350
47 + 31627303 = 31627350
61 + 31627289 = 31627350
89 + 31627261 = 31627350
101 + 31627249 = 31627350
103 + 31627247 = 31627350
107 + 31627243 = 31627350

Showing the first eight; more decompositions exist.
