Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509662, here are decompositions:

3 + 31509659 = 31509662
61 + 31509601 = 31509662
109 + 31509553 = 31509662
139 + 31509523 = 31509662
193 + 31509469 = 31509662
229 + 31509433 = 31509662
313 + 31509349 = 31509662
523 + 31509139 = 31509662

Showing the first eight; more decompositions exist.
