Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743972, here are decompositions:

53 + 8743919 = 8743972
59 + 8743913 = 8743972
71 + 8743901 = 8743972
89 + 8743883 = 8743972
239 + 8743733 = 8743972
383 + 8743589 = 8743972
389 + 8743583 = 8743972
401 + 8743571 = 8743972

Showing the first eight; more decompositions exist.
