Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523794, here are decompositions:

41 + 31523753 = 31523794
257 + 31523537 = 31523794
317 + 31523477 = 31523794
353 + 31523441 = 31523794
383 + 31523411 = 31523794
557 + 31523237 = 31523794
563 + 31523231 = 31523794
587 + 31523207 = 31523794

Showing the first eight; more decompositions exist.
