Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567510, here are decompositions:

59 + 31567451 = 31567510
83 + 31567427 = 31567510
113 + 31567397 = 31567510
197 + 31567313 = 31567510
239 + 31567271 = 31567510
269 + 31567241 = 31567510
353 + 31567157 = 31567510
419 + 31567091 = 31567510

Showing the first eight; more decompositions exist.
