Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589946, here are decompositions:

23 + 31589923 = 31589946
79 + 31589867 = 31589946
103 + 31589843 = 31589946
127 + 31589819 = 31589946
173 + 31589773 = 31589946
239 + 31589707 = 31589946
263 + 31589683 = 31589946
313 + 31589633 = 31589946

Showing the first eight; more decompositions exist.
