Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744138, here are decompositions:

37 + 8744101 = 8744138
97 + 8744041 = 8744138
157 + 8743981 = 8744138
331 + 8743807 = 8744138
367 + 8743771 = 8744138
421 + 8743717 = 8744138
457 + 8743681 = 8744138
499 + 8743639 = 8744138

Showing the first eight; more decompositions exist.
