Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589276, here are decompositions:

79 + 31589197 = 31589276
109 + 31589167 = 31589276
139 + 31589137 = 31589276
157 + 31589119 = 31589276
283 + 31588993 = 31589276
349 + 31588927 = 31589276
379 + 31588897 = 31589276
463 + 31588813 = 31589276

Showing the first eight; more decompositions exist.
