Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533502, here are decompositions:

3 + 31533499 = 31533502
5 + 31533497 = 31533502
41 + 31533461 = 31533502
53 + 31533449 = 31533502
71 + 31533431 = 31533502
89 + 31533413 = 31533502
113 + 31533389 = 31533502
131 + 31533371 = 31533502

Showing the first eight; more decompositions exist.
