Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690120, here are decompositions:

3 + 8690117 = 8690120
31 + 8690089 = 8690120
79 + 8690041 = 8690120
139 + 8689981 = 8690120
151 + 8689969 = 8690120
163 + 8689957 = 8690120
277 + 8689843 = 8690120
367 + 8689753 = 8690120

Showing the first eight; more decompositions exist.
