Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500670, here are decompositions:

11 + 31500659 = 31500670
59 + 31500611 = 31500670
101 + 31500569 = 31500670
167 + 31500503 = 31500670
251 + 31500419 = 31500670
263 + 31500407 = 31500670
293 + 31500377 = 31500670
317 + 31500353 = 31500670

Showing the first eight; more decompositions exist.
