Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592404, here are decompositions:

47 + 31592357 = 31592404
113 + 31592291 = 31592404
191 + 31592213 = 31592404
281 + 31592123 = 31592404
353 + 31592051 = 31592404
491 + 31591913 = 31592404
653 + 31591751 = 31592404
827 + 31591577 = 31592404

Showing the first eight; more decompositions exist.
