Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619626, here are decompositions:

3 + 8619623 = 8619626
157 + 8619469 = 8619626
193 + 8619433 = 8619626
199 + 8619427 = 8619626
229 + 8619397 = 8619626
283 + 8619343 = 8619626
397 + 8619229 = 8619626
709 + 8618917 = 8619626

Showing the first eight; more decompositions exist.
