Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594002, here are decompositions:

19 + 31593983 = 31594002
43 + 31593959 = 31594002
59 + 31593943 = 31594002
71 + 31593931 = 31594002
101 + 31593901 = 31594002
163 + 31593839 = 31594002
239 + 31593763 = 31594002
281 + 31593721 = 31594002

Showing the first eight; more decompositions exist.
