Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599722, here are decompositions:

19 + 31599703 = 31599722
73 + 31599649 = 31599722
223 + 31599499 = 31599722
283 + 31599439 = 31599722
373 + 31599349 = 31599722
409 + 31599313 = 31599722
463 + 31599259 = 31599722
619 + 31599103 = 31599722

Showing the first eight; more decompositions exist.
