Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462550, here are decompositions:

3 + 31462547 = 31462550
19 + 31462531 = 31462550
43 + 31462507 = 31462550
79 + 31462471 = 31462550
109 + 31462441 = 31462550
193 + 31462357 = 31462550
199 + 31462351 = 31462550
211 + 31462339 = 31462550

Showing the first eight; more decompositions exist.
