Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511662, here are decompositions:

11 + 31511651 = 31511662
113 + 31511549 = 31511662
179 + 31511483 = 31511662
191 + 31511471 = 31511662
239 + 31511423 = 31511662
401 + 31511261 = 31511662
431 + 31511231 = 31511662
449 + 31511213 = 31511662

Showing the first eight; more decompositions exist.
