Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599542, here are decompositions:

43 + 31599499 = 31599542
103 + 31599439 = 31599542
193 + 31599349 = 31599542
229 + 31599313 = 31599542
283 + 31599259 = 31599542
349 + 31599193 = 31599542
439 + 31599103 = 31599542
619 + 31598923 = 31599542

Showing the first eight; more decompositions exist.
