Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749958, here are decompositions:

31 + 8749927 = 8749958
37 + 8749921 = 8749958
67 + 8749891 = 8749958
307 + 8749651 = 8749958
331 + 8749627 = 8749958
379 + 8749579 = 8749958
409 + 8749549 = 8749958
541 + 8749417 = 8749958

Showing the first eight; more decompositions exist.
