Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749972, here are decompositions:

131 + 8749841 = 8749972
239 + 8749733 = 8749972
359 + 8749613 = 8749972
383 + 8749589 = 8749972
401 + 8749571 = 8749972
503 + 8749469 = 8749972
521 + 8749451 = 8749972
641 + 8749331 = 8749972

Showing the first eight; more decompositions exist.
