Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472834, here are decompositions:

7 + 31472827 = 31472834
61 + 31472773 = 31472834
223 + 31472611 = 31472834
397 + 31472437 = 31472834
541 + 31472293 = 31472834
643 + 31472191 = 31472834
691 + 31472143 = 31472834
727 + 31472107 = 31472834

Showing the first eight; more decompositions exist.
