Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599294, here are decompositions:

47 + 31599247 = 31599294
101 + 31599193 = 31599294
137 + 31599157 = 31599294
191 + 31599103 = 31599294
193 + 31599101 = 31599294
347 + 31598947 = 31599294
367 + 31598927 = 31599294
383 + 31598911 = 31599294

Showing the first eight; more decompositions exist.
