Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740742, here are decompositions:

61 + 8740681 = 8740742
139 + 8740603 = 8740742
151 + 8740591 = 8740742
163 + 8740579 = 8740742
181 + 8740561 = 8740742
211 + 8740531 = 8740742
223 + 8740519 = 8740742
313 + 8740429 = 8740742

Showing the first eight; more decompositions exist.
