Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599524, here are decompositions:

37 + 31599487 = 31599524
211 + 31599313 = 31599524
277 + 31599247 = 31599524
331 + 31599193 = 31599524
367 + 31599157 = 31599524
421 + 31599103 = 31599524
571 + 31598953 = 31599524
577 + 31598947 = 31599524

Showing the first eight; more decompositions exist.
