Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500682, here are decompositions:

23 + 31500659 = 31500682
71 + 31500611 = 31500682
113 + 31500569 = 31500682
173 + 31500509 = 31500682
179 + 31500503 = 31500682
263 + 31500419 = 31500682
401 + 31500281 = 31500682
419 + 31500263 = 31500682

Showing the first eight; more decompositions exist.
