Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725122, here are decompositions:

11 + 8725111 = 8725122
19 + 8725103 = 8725122
23 + 8725099 = 8725122
31 + 8725091 = 8725122
71 + 8725051 = 8725122
83 + 8725039 = 8725122
101 + 8725021 = 8725122
139 + 8724983 = 8725122

Showing the first eight; more decompositions exist.
