Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749028, here are decompositions:

37 + 8748991 = 8749028
139 + 8748889 = 8749028
151 + 8748877 = 8749028
181 + 8748847 = 8749028
241 + 8748787 = 8749028
439 + 8748589 = 8749028
661 + 8748367 = 8749028
751 + 8748277 = 8749028

Showing the first eight; more decompositions exist.
