Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738972, here are decompositions:

43 + 8738929 = 8738972
163 + 8738809 = 8738972
313 + 8738659 = 8738972
331 + 8738641 = 8738972
433 + 8738539 = 8738972
439 + 8738533 = 8738972
499 + 8738473 = 8738972
523 + 8738449 = 8738972

Showing the first eight; more decompositions exist.
