Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671778, here are decompositions:

67 + 8671711 = 8671778
109 + 8671669 = 8671778
139 + 8671639 = 8671778
229 + 8671549 = 8671778
277 + 8671501 = 8671778
307 + 8671471 = 8671778
331 + 8671447 = 8671778
337 + 8671441 = 8671778

Showing the first eight; more decompositions exist.
