Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749980, here are decompositions:

53 + 8749927 = 8749980
59 + 8749921 = 8749980
89 + 8749891 = 8749980
139 + 8749841 = 8749980
163 + 8749817 = 8749980
167 + 8749813 = 8749980
191 + 8749789 = 8749980
193 + 8749787 = 8749980

Showing the first eight; more decompositions exist.
