Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738980, here are decompositions:

17 + 8738963 = 8738980
23 + 8738957 = 8738980
137 + 8738843 = 8738980
167 + 8738813 = 8738980
179 + 8738801 = 8738980
197 + 8738783 = 8738980
251 + 8738729 = 8738980
269 + 8738711 = 8738980

Showing the first eight; more decompositions exist.
