Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592048, here are decompositions:

139 + 31591909 = 31592048
181 + 31591867 = 31592048
211 + 31591837 = 31592048
337 + 31591711 = 31592048
571 + 31591477 = 31592048
601 + 31591447 = 31592048
757 + 31591291 = 31592048
877 + 31591171 = 31592048

Showing the first eight; more decompositions exist.
