Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509026, here are decompositions:

67 + 31508959 = 31509026
79 + 31508947 = 31509026
139 + 31508887 = 31509026
163 + 31508863 = 31509026
313 + 31508713 = 31509026
349 + 31508677 = 31509026
379 + 31508647 = 31509026
457 + 31508569 = 31509026

Showing the first eight; more decompositions exist.
