Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533498, here are decompositions:

37 + 31533461 = 31533498
47 + 31533451 = 31533498
67 + 31533431 = 31533498
89 + 31533409 = 31533498
109 + 31533389 = 31533498
127 + 31533371 = 31533498
229 + 31533269 = 31533498
239 + 31533259 = 31533498

Showing the first eight; more decompositions exist.
