Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599442, here are decompositions:

3 + 31599439 = 31599442
11 + 31599431 = 31599442
53 + 31599389 = 31599442
89 + 31599353 = 31599442
101 + 31599341 = 31599442
269 + 31599173 = 31599442
383 + 31599059 = 31599442
503 + 31598939 = 31599442

Showing the first eight; more decompositions exist.
