Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533510, here are decompositions:

11 + 31533499 = 31533510
13 + 31533497 = 31533510
59 + 31533451 = 31533510
61 + 31533449 = 31533510
79 + 31533431 = 31533510
97 + 31533413 = 31533510
101 + 31533409 = 31533510
131 + 31533379 = 31533510

Showing the first eight; more decompositions exist.
