Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743448, here are decompositions:

31 + 8743417 = 8743448
37 + 8743411 = 8743448
139 + 8743309 = 8743448
349 + 8743099 = 8743448
421 + 8743027 = 8743448
601 + 8742847 = 8743448
631 + 8742817 = 8743448
661 + 8742787 = 8743448

Showing the first eight; more decompositions exist.
