Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594992, here are decompositions:

5 + 31594987 = 31594992
29 + 31594963 = 31594992
31 + 31594961 = 31594992
61 + 31594931 = 31594992
73 + 31594919 = 31594992
89 + 31594903 = 31594992
109 + 31594883 = 31594992
131 + 31594861 = 31594992

Showing the first eight; more decompositions exist.
