Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687020, here are decompositions:

59 + 8686961 = 8687020
131 + 8686889 = 8687020
137 + 8686883 = 8687020
179 + 8686841 = 8687020
191 + 8686829 = 8687020
317 + 8686703 = 8687020
359 + 8686661 = 8687020
431 + 8686589 = 8687020

Showing the first eight; more decompositions exist.
