Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691250, here are decompositions:

3 + 8691247 = 8691250
11 + 8691239 = 8691250
41 + 8691209 = 8691250
83 + 8691167 = 8691250
131 + 8691119 = 8691250
149 + 8691101 = 8691250
383 + 8690867 = 8691250
461 + 8690789 = 8691250

Showing the first eight; more decompositions exist.
