Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592582, here are decompositions:

31 + 31592551 = 31592582
193 + 31592389 = 31592582
271 + 31592311 = 31592582
379 + 31592203 = 31592582
409 + 31592173 = 31592582
421 + 31592161 = 31592582
433 + 31592149 = 31592582
673 + 31591909 = 31592582

Showing the first eight; more decompositions exist.
