Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592408, here are decompositions:

19 + 31592389 = 31592408
31 + 31592377 = 31592408
61 + 31592347 = 31592408
97 + 31592311 = 31592408
151 + 31592257 = 31592408
409 + 31591999 = 31592408
499 + 31591909 = 31592408
541 + 31591867 = 31592408

Showing the first eight; more decompositions exist.
