Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761142, here are decompositions:

3 + 8761139 = 8761142
43 + 8761099 = 8761142
151 + 8760991 = 8761142
241 + 8760901 = 8761142
331 + 8760811 = 8761142
421 + 8760721 = 8761142
571 + 8760571 = 8761142
661 + 8760481 = 8761142

Showing the first eight; more decompositions exist.
