Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740928, here are decompositions:

37 + 8740891 = 8740928
61 + 8740867 = 8740928
139 + 8740789 = 8740928
271 + 8740657 = 8740928
337 + 8740591 = 8740928
349 + 8740579 = 8740928
367 + 8740561 = 8740928
397 + 8740531 = 8740928

Showing the first eight; more decompositions exist.
