Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592712, here are decompositions:

29 + 31592683 = 31592712
61 + 31592651 = 31592712
71 + 31592641 = 31592712
113 + 31592599 = 31592712
181 + 31592531 = 31592712
223 + 31592489 = 31592712
401 + 31592311 = 31592712
421 + 31592291 = 31592712

Showing the first eight; more decompositions exist.
