Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740442, here are decompositions:

13 + 8740429 = 8740442
31 + 8740411 = 8740442
223 + 8740219 = 8740442
313 + 8740129 = 8740442
331 + 8740111 = 8740442
439 + 8740003 = 8740442
523 + 8739919 = 8740442
541 + 8739901 = 8740442

Showing the first eight; more decompositions exist.
