Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712958, here are decompositions:

131 + 8712827 = 8712958
179 + 8712779 = 8712958
197 + 8712761 = 8712958
257 + 8712701 = 8712958
281 + 8712677 = 8712958
347 + 8712611 = 8712958
461 + 8712497 = 8712958
467 + 8712491 = 8712958

Showing the first eight; more decompositions exist.
