Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610662, here are decompositions:

23 + 31610639 = 31610662
89 + 31610573 = 31610662
101 + 31610561 = 31610662
269 + 31610393 = 31610662
383 + 31610279 = 31610662
431 + 31610231 = 31610662
449 + 31610213 = 31610662
491 + 31610171 = 31610662

Showing the first eight; more decompositions exist.
