Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592678, here are decompositions:

37 + 31592641 = 31592678
79 + 31592599 = 31592678
127 + 31592551 = 31592678
211 + 31592467 = 31592678
241 + 31592437 = 31592678
331 + 31592347 = 31592678
367 + 31592311 = 31592678
421 + 31592257 = 31592678

Showing the first eight; more decompositions exist.
