Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546930, here are decompositions:

17 + 31546913 = 31546930
83 + 31546847 = 31546930
113 + 31546817 = 31546930
131 + 31546799 = 31546930
269 + 31546661 = 31546930
293 + 31546637 = 31546930
347 + 31546583 = 31546930
461 + 31546469 = 31546930

Showing the first eight; more decompositions exist.
