Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677808, here are decompositions:

37 + 8677771 = 8677808
127 + 8677681 = 8677808
157 + 8677651 = 8677808
331 + 8677477 = 8677808
409 + 8677399 = 8677808
421 + 8677387 = 8677808
541 + 8677267 = 8677808
547 + 8677261 = 8677808

Showing the first eight; more decompositions exist.
