Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592426, here are decompositions:

3 + 31592423 = 31592426
37 + 31592389 = 31592426
79 + 31592347 = 31592426
223 + 31592203 = 31592426
277 + 31592149 = 31592426
373 + 31592053 = 31592426
379 + 31592047 = 31592426
433 + 31591993 = 31592426

Showing the first eight; more decompositions exist.
