Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749940, here are decompositions:

13 + 8749927 = 8749940
19 + 8749921 = 8749940
37 + 8749903 = 8749940
103 + 8749837 = 8749940
127 + 8749813 = 8749940
151 + 8749789 = 8749940
271 + 8749669 = 8749940
313 + 8749627 = 8749940

Showing the first eight; more decompositions exist.
