Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761688, here are decompositions:

151 + 8761537 = 8761688
157 + 8761531 = 8761688
181 + 8761507 = 8761688
349 + 8761339 = 8761688
409 + 8761279 = 8761688
547 + 8761141 = 8761688
571 + 8761117 = 8761688
787 + 8760901 = 8761688

Showing the first eight; more decompositions exist.
