Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523502, here are decompositions:

29 + 31523473 = 31523502
41 + 31523461 = 31523502
61 + 31523441 = 31523502
83 + 31523419 = 31523502
103 + 31523399 = 31523502
173 + 31523329 = 31523502
193 + 31523309 = 31523502
223 + 31523279 = 31523502

Showing the first eight; more decompositions exist.
