Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592288, here are decompositions:

31 + 31592257 = 31592288
127 + 31592161 = 31592288
139 + 31592149 = 31592288
241 + 31592047 = 31592288
331 + 31591957 = 31592288
379 + 31591909 = 31592288
421 + 31591867 = 31592288
577 + 31591711 = 31592288

Showing the first eight; more decompositions exist.
