Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612122, here are decompositions:

3 + 8612119 = 8612122
23 + 8612099 = 8612122
83 + 8612039 = 8612122
89 + 8612033 = 8612122
131 + 8611991 = 8612122
263 + 8611859 = 8612122
293 + 8611829 = 8612122
401 + 8611721 = 8612122

Showing the first eight; more decompositions exist.
