Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619980, here are decompositions:

37 + 8619943 = 8619980
43 + 8619937 = 8619980
97 + 8619883 = 8619980
163 + 8619817 = 8619980
331 + 8619649 = 8619980
379 + 8619601 = 8619980
541 + 8619439 = 8619980
547 + 8619433 = 8619980

Showing the first eight; more decompositions exist.
