Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592108, here are decompositions:

61 + 31592047 = 31592108
109 + 31591999 = 31592108
151 + 31591957 = 31592108
199 + 31591909 = 31592108
241 + 31591867 = 31592108
271 + 31591837 = 31592108
397 + 31591711 = 31592108
421 + 31591687 = 31592108

Showing the first eight; more decompositions exist.
