Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592468, here are decompositions:

31 + 31592437 = 31592468
79 + 31592389 = 31592468
157 + 31592311 = 31592468
211 + 31592257 = 31592468
307 + 31592161 = 31592468
421 + 31592047 = 31592468
601 + 31591867 = 31592468
631 + 31591837 = 31592468

Showing the first eight; more decompositions exist.
