Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742980, here are decompositions:

3 + 8742977 = 8742980
7 + 8742973 = 8742980
61 + 8742919 = 8742980
163 + 8742817 = 8742980
193 + 8742787 = 8742980
241 + 8742739 = 8742980
307 + 8742673 = 8742980
409 + 8742571 = 8742980

Showing the first eight; more decompositions exist.
