Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594040, here are decompositions:

97 + 31593943 = 31594040
103 + 31593937 = 31594040
109 + 31593931 = 31594040
139 + 31593901 = 31594040
277 + 31593763 = 31594040
337 + 31593703 = 31594040
397 + 31593643 = 31594040
409 + 31593631 = 31594040

Showing the first eight; more decompositions exist.
