Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619090, here are decompositions:

13 + 8619077 = 8619090
19 + 8619071 = 8619090
23 + 8619067 = 8619090
31 + 8619059 = 8619090
37 + 8619053 = 8619090
59 + 8619031 = 8619090
131 + 8618959 = 8619090
157 + 8618933 = 8619090

Showing the first eight; more decompositions exist.
