Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454550, here are decompositions:

37 + 31454513 = 31454550
53 + 31454497 = 31454550
67 + 31454483 = 31454550
89 + 31454461 = 31454550
109 + 31454441 = 31454550
167 + 31454383 = 31454550
173 + 31454377 = 31454550
199 + 31454351 = 31454550

Showing the first eight; more decompositions exist.
