Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626972, here are decompositions:

71 + 8626901 = 8626972
131 + 8626841 = 8626972
149 + 8626823 = 8626972
239 + 8626733 = 8626972
281 + 8626691 = 8626972
359 + 8626613 = 8626972
443 + 8626529 = 8626972
479 + 8626493 = 8626972

Showing the first eight; more decompositions exist.
