Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594184, here are decompositions:

103 + 31594081 = 31594184
241 + 31593943 = 31594184
283 + 31593901 = 31594184
397 + 31593787 = 31594184
421 + 31593763 = 31594184
463 + 31593721 = 31594184
541 + 31593643 = 31594184
571 + 31593613 = 31594184

Showing the first eight; more decompositions exist.
