Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736778, here are decompositions:

59 + 8736719 = 8736778
131 + 8736647 = 8736778
269 + 8736509 = 8736778
317 + 8736461 = 8736778
569 + 8736209 = 8736778
587 + 8736191 = 8736778
599 + 8736179 = 8736778
719 + 8736059 = 8736778

Showing the first eight; more decompositions exist.
