Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594070, here are decompositions:

7 + 31594063 = 31594070
31 + 31594039 = 31594070
127 + 31593943 = 31594070
139 + 31593931 = 31594070
283 + 31593787 = 31594070
307 + 31593763 = 31594070
349 + 31593721 = 31594070
367 + 31593703 = 31594070

Showing the first eight; more decompositions exist.
