Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748440, here are decompositions:

37 + 8748403 = 8748440
73 + 8748367 = 8748440
79 + 8748361 = 8748440
109 + 8748331 = 8748440
163 + 8748277 = 8748440
241 + 8748199 = 8748440
331 + 8748109 = 8748440
397 + 8748043 = 8748440

Showing the first eight; more decompositions exist.
