Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746778, here are decompositions:

127 + 8746651 = 8746778
331 + 8746447 = 8746778
379 + 8746399 = 8746778
409 + 8746369 = 8746778
421 + 8746357 = 8746778
541 + 8746237 = 8746778
571 + 8746207 = 8746778
661 + 8746117 = 8746778

Showing the first eight; more decompositions exist.
