Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641202, here are decompositions:

109 + 8641093 = 8641202
139 + 8641063 = 8641202
313 + 8640889 = 8641202
331 + 8640871 = 8641202
379 + 8640823 = 8641202
421 + 8640781 = 8641202
463 + 8640739 = 8641202
499 + 8640703 = 8641202

Showing the first eight; more decompositions exist.
