Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599306, here are decompositions:

47 + 31599259 = 31599306
59 + 31599247 = 31599306
113 + 31599193 = 31599306
149 + 31599157 = 31599306
317 + 31598989 = 31599306
353 + 31598953 = 31599306
359 + 31598947 = 31599306
367 + 31598939 = 31599306

Showing the first eight; more decompositions exist.
