Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599848, here are decompositions:

37 + 31599811 = 31599848
67 + 31599781 = 31599848
199 + 31599649 = 31599848
349 + 31599499 = 31599848
409 + 31599439 = 31599848
499 + 31599349 = 31599848
541 + 31599307 = 31599848
601 + 31599247 = 31599848

Showing the first eight; more decompositions exist.
