Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528502, here are decompositions:

3 + 31528499 = 31528502
43 + 31528459 = 31528502
139 + 31528363 = 31528502
211 + 31528291 = 31528502
223 + 31528279 = 31528502
331 + 31528171 = 31528502
409 + 31528093 = 31528502
433 + 31528069 = 31528502

Showing the first eight; more decompositions exist.
