Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744072, here are decompositions:

31 + 8744041 = 8744072
109 + 8743963 = 8744072
193 + 8743879 = 8744072
229 + 8743843 = 8744072
433 + 8743639 = 8744072
439 + 8743633 = 8744072
523 + 8743549 = 8744072
541 + 8743531 = 8744072

Showing the first eight; more decompositions exist.
