Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592882, here are decompositions:

73 + 31592809 = 31592882
103 + 31592779 = 31592882
109 + 31592773 = 31592882
199 + 31592683 = 31592882
241 + 31592641 = 31592882
283 + 31592599 = 31592882
331 + 31592551 = 31592882
571 + 31592311 = 31592882

Showing the first eight; more decompositions exist.
