Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744490, here are decompositions:

23 + 8744467 = 8744490
31 + 8744459 = 8744490
43 + 8744447 = 8744490
67 + 8744423 = 8744490
71 + 8744419 = 8744490
173 + 8744317 = 8744490
193 + 8744297 = 8744490
229 + 8744261 = 8744490

Showing the first eight; more decompositions exist.
