Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31521034, here are decompositions:

3 + 31521031 = 31521034
5 + 31521029 = 31521034
137 + 31520897 = 31521034
173 + 31520861 = 31521034
197 + 31520837 = 31521034
617 + 31520417 = 31521034
641 + 31520393 = 31521034
647 + 31520387 = 31521034

Showing the first eight; more decompositions exist.
