Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744242, here are decompositions:

53 + 8744189 = 8744242
113 + 8744129 = 8744242
179 + 8744063 = 8744242
239 + 8744003 = 8744242
251 + 8743991 = 8744242
359 + 8743883 = 8744242
389 + 8743853 = 8744242
509 + 8743733 = 8744242

Showing the first eight; more decompositions exist.
