Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598472, here are decompositions:

13 + 31598459 = 31598472
23 + 31598449 = 31598472
53 + 31598419 = 31598472
71 + 31598401 = 31598472
109 + 31598363 = 31598472
151 + 31598321 = 31598472
173 + 31598299 = 31598472
193 + 31598279 = 31598472

Showing the first eight; more decompositions exist.
