Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594130, here are decompositions:

67 + 31594063 = 31594130
193 + 31593937 = 31594130
199 + 31593931 = 31594130
229 + 31593901 = 31594130
367 + 31593763 = 31594130
409 + 31593721 = 31594130
487 + 31593643 = 31594130
499 + 31593631 = 31594130

Showing the first eight; more decompositions exist.
