Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748428, here are decompositions:

61 + 8748367 = 8748428
67 + 8748361 = 8748428
97 + 8748331 = 8748428
151 + 8748277 = 8748428
229 + 8748199 = 8748428
331 + 8748097 = 8748428
397 + 8748031 = 8748428
457 + 8747971 = 8748428

Showing the first eight; more decompositions exist.
