Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520634, here are decompositions:

7 + 31520627 = 31520634
17 + 31520617 = 31520634
53 + 31520581 = 31520634
97 + 31520537 = 31520634
107 + 31520527 = 31520634
137 + 31520497 = 31520634
151 + 31520483 = 31520634
181 + 31520453 = 31520634

Showing the first eight; more decompositions exist.
