Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749982, here are decompositions:

61 + 8749921 = 8749982
79 + 8749903 = 8749982
193 + 8749789 = 8749982
211 + 8749771 = 8749982
229 + 8749753 = 8749982
313 + 8749669 = 8749982
331 + 8749651 = 8749982
379 + 8749603 = 8749982

Showing the first eight; more decompositions exist.
