Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499368, here are decompositions:

41 + 31499327 = 31499368
59 + 31499309 = 31499368
71 + 31499297 = 31499368
101 + 31499267 = 31499368
137 + 31499231 = 31499368
179 + 31499189 = 31499368
311 + 31499057 = 31499368
347 + 31499021 = 31499368

Showing the first eight; more decompositions exist.
