Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599174, here are decompositions:

17 + 31599157 = 31599174
71 + 31599103 = 31599174
73 + 31599101 = 31599174
227 + 31598947 = 31599174
241 + 31598933 = 31599174
251 + 31598923 = 31599174
263 + 31598911 = 31599174
307 + 31598867 = 31599174

Showing the first eight; more decompositions exist.
