Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599648, here are decompositions:

19 + 31599629 = 31599648
37 + 31599611 = 31599648
97 + 31599551 = 31599648
149 + 31599499 = 31599648
307 + 31599341 = 31599648
389 + 31599259 = 31599648
401 + 31599247 = 31599648
491 + 31599157 = 31599648

Showing the first eight; more decompositions exist.
