Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623742, here are decompositions:

13 + 8623729 = 8623742
103 + 8623639 = 8623742
139 + 8623603 = 8623742
163 + 8623579 = 8623742
223 + 8623519 = 8623742
313 + 8623429 = 8623742
349 + 8623393 = 8623742
601 + 8623141 = 8623742

Showing the first eight; more decompositions exist.
