Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459502, here are decompositions:

3 + 31459499 = 31459502
103 + 31459399 = 31459502
163 + 31459339 = 31459502
181 + 31459321 = 31459502
211 + 31459291 = 31459502
241 + 31459261 = 31459502
379 + 31459123 = 31459502
409 + 31459093 = 31459502

Showing the first eight; more decompositions exist.
