Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500652, here are decompositions:

3 + 31500649 = 31500652
41 + 31500611 = 31500652
83 + 31500569 = 31500652
149 + 31500503 = 31500652
233 + 31500419 = 31500652
269 + 31500383 = 31500652
389 + 31500263 = 31500652
431 + 31500221 = 31500652

Showing the first eight; more decompositions exist.
