Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592028, here are decompositions:

29 + 31591999 = 31592028
31 + 31591997 = 31592028
71 + 31591957 = 31592028
191 + 31591837 = 31592028
277 + 31591751 = 31592028
317 + 31591711 = 31592028
379 + 31591649 = 31592028
431 + 31591597 = 31592028

Showing the first eight; more decompositions exist.
