Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592726, here are decompositions:

43 + 31592683 = 31592726
127 + 31592599 = 31592726
337 + 31592389 = 31592726
349 + 31592377 = 31592726
379 + 31592347 = 31592726
523 + 31592203 = 31592726
577 + 31592149 = 31592726
673 + 31592053 = 31592726

Showing the first eight; more decompositions exist.
