Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547032, here are decompositions:

29 + 31547003 = 31547032
233 + 31546799 = 31547032
311 + 31546721 = 31547032
431 + 31546601 = 31547032
449 + 31546583 = 31547032
479 + 31546553 = 31547032
563 + 31546469 = 31547032
683 + 31546349 = 31547032

Showing the first eight; more decompositions exist.
