Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749942, here are decompositions:

101 + 8749841 = 8749942
191 + 8749751 = 8749942
353 + 8749589 = 8749942
491 + 8749451 = 8749942
503 + 8749439 = 8749942
521 + 8749421 = 8749942
599 + 8749343 = 8749942
743 + 8749199 = 8749942

Showing the first eight; more decompositions exist.
