Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592706, here are decompositions:

23 + 31592683 = 31592706
29 + 31592677 = 31592706
43 + 31592663 = 31592706
107 + 31592599 = 31592706
139 + 31592567 = 31592706
149 + 31592557 = 31592706
239 + 31592467 = 31592706
269 + 31592437 = 31592706

Showing the first eight; more decompositions exist.
