Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740220, here are decompositions:

37 + 8740183 = 8740220
103 + 8740117 = 8740220
109 + 8740111 = 8740220
283 + 8739937 = 8740220
337 + 8739883 = 8740220
397 + 8739823 = 8740220
409 + 8739811 = 8740220
499 + 8739721 = 8740220

Showing the first eight; more decompositions exist.
