Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749898, here are decompositions:

7 + 8749891 = 8749898
61 + 8749837 = 8749898
109 + 8749789 = 8749898
127 + 8749771 = 8749898
229 + 8749669 = 8749898
271 + 8749627 = 8749898
349 + 8749549 = 8749898
541 + 8749357 = 8749898

Showing the first eight; more decompositions exist.
