Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594004, here are decompositions:

61 + 31593943 = 31594004
67 + 31593937 = 31594004
73 + 31593931 = 31594004
103 + 31593901 = 31594004
241 + 31593763 = 31594004
283 + 31593721 = 31594004
373 + 31593631 = 31594004
397 + 31593607 = 31594004

Showing the first eight; more decompositions exist.
