Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744402, here are decompositions:

211 + 8744191 = 8744402
379 + 8744023 = 8744402
421 + 8743981 = 8744402
439 + 8743963 = 8744402
523 + 8743879 = 8744402
631 + 8743771 = 8744402
691 + 8743711 = 8744402
769 + 8743633 = 8744402

Showing the first eight; more decompositions exist.
