Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529002, here are decompositions:

5 + 31528997 = 31529002
149 + 31528853 = 31529002
179 + 31528823 = 31529002
191 + 31528811 = 31529002
251 + 31528751 = 31529002
389 + 31528613 = 31529002
443 + 31528559 = 31529002
503 + 31528499 = 31529002

Showing the first eight; more decompositions exist.
