Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533608, here are decompositions:

37 + 31533571 = 31533608
61 + 31533547 = 31533608
97 + 31533511 = 31533608
109 + 31533499 = 31533608
157 + 31533451 = 31533608
199 + 31533409 = 31533608
229 + 31533379 = 31533608
349 + 31533259 = 31533608

Showing the first eight; more decompositions exist.
