Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761742, here are decompositions:

103 + 8761639 = 8761742
109 + 8761633 = 8761742
211 + 8761531 = 8761742
313 + 8761429 = 8761742
439 + 8761303 = 8761742
463 + 8761279 = 8761742
499 + 8761243 = 8761742
601 + 8761141 = 8761742

Showing the first eight; more decompositions exist.
