Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589246, here are decompositions:

79 + 31589167 = 31589246
109 + 31589137 = 31589246
127 + 31589119 = 31589246
229 + 31589017 = 31589246
313 + 31588933 = 31589246
349 + 31588897 = 31589246
433 + 31588813 = 31589246
439 + 31588807 = 31589246

Showing the first eight; more decompositions exist.
