Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749642, here are decompositions:

29 + 8749613 = 8749642
53 + 8749589 = 8749642
71 + 8749571 = 8749642
173 + 8749469 = 8749642
191 + 8749451 = 8749642
311 + 8749331 = 8749642
443 + 8749199 = 8749642
479 + 8749163 = 8749642

Showing the first eight; more decompositions exist.
