Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584350, here are decompositions:

13 + 31584337 = 31584350
43 + 31584307 = 31584350
103 + 31584247 = 31584350
139 + 31584211 = 31584350
157 + 31584193 = 31584350
211 + 31584139 = 31584350
283 + 31584067 = 31584350
307 + 31584043 = 31584350

Showing the first eight; more decompositions exist.
