Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547092, here are decompositions:

29 + 31547063 = 31547092
53 + 31547039 = 31547092
89 + 31547003 = 31547092
179 + 31546913 = 31547092
293 + 31546799 = 31547092
383 + 31546709 = 31547092
431 + 31546661 = 31547092
491 + 31546601 = 31547092

Showing the first eight; more decompositions exist.
