Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 941840, here are decompositions:

103 + 941737 = 941840
139 + 941701 = 941840
157 + 941683 = 941840
199 + 941641 = 941840
223 + 941617 = 941840
241 + 941599 = 941840
283 + 941557 = 941840
331 + 941509 = 941840

Showing the first eight; more decompositions exist.
