Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499094, here are decompositions:

17 + 31499077 = 31499094
31 + 31499063 = 31499094
37 + 31499057 = 31499094
61 + 31499033 = 31499094
71 + 31499023 = 31499094
73 + 31499021 = 31499094
101 + 31498993 = 31499094
103 + 31498991 = 31499094

Showing the first eight; more decompositions exist.
