Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567600, here are decompositions:

41 + 31567559 = 31567600
47 + 31567553 = 31567600
89 + 31567511 = 31567600
149 + 31567451 = 31567600
173 + 31567427 = 31567600
359 + 31567241 = 31567600
443 + 31567157 = 31567600
509 + 31567091 = 31567600

Showing the first eight; more decompositions exist.
