Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740142, here are decompositions:

3 + 8740139 = 8740142
13 + 8740129 = 8740142
31 + 8740111 = 8740142
139 + 8740003 = 8740142
181 + 8739961 = 8740142
223 + 8739919 = 8740142
241 + 8739901 = 8740142
331 + 8739811 = 8740142

Showing the first eight; more decompositions exist.
