Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592768, here are decompositions:

7 + 31592761 = 31592768
127 + 31592641 = 31592768
211 + 31592557 = 31592768
331 + 31592437 = 31592768
379 + 31592389 = 31592768
421 + 31592347 = 31592768
457 + 31592311 = 31592768
607 + 31592161 = 31592768

Showing the first eight; more decompositions exist.
