Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043618, here are decompositions:

19 + 1043599 = 1043618
31 + 1043587 = 1043618
61 + 1043557 = 1043618
97 + 1043521 = 1043618
139 + 1043479 = 1043618
151 + 1043467 = 1043618
241 + 1043377 = 1043618
307 + 1043311 = 1043618

Showing the first eight; more decompositions exist.
