Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743442, here are decompositions:

31 + 8743411 = 8743442
163 + 8743279 = 8743442
181 + 8743261 = 8743442
229 + 8743213 = 8743442
523 + 8742919 = 8743442
769 + 8742673 = 8743442
1021 + 8742421 = 8743442
1063 + 8742379 = 8743442

Showing the first eight; more decompositions exist.
