Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740028, here are decompositions:

61 + 8739967 = 8740028
67 + 8739961 = 8740028
109 + 8739919 = 8740028
127 + 8739901 = 8740028
151 + 8739877 = 8740028
307 + 8739721 = 8740028
421 + 8739607 = 8740028
499 + 8739529 = 8740028

Showing the first eight; more decompositions exist.
