Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509034, here are decompositions:

3 + 31509031 = 31509034
5 + 31509029 = 31509034
17 + 31509017 = 31509034
113 + 31508921 = 31509034
191 + 31508843 = 31509034
353 + 31508681 = 31509034
383 + 31508651 = 31509034
467 + 31508567 = 31509034

Showing the first eight; more decompositions exist.
