Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740844, here are decompositions:

3 + 8740841 = 8740844
37 + 8740807 = 8740844
61 + 8740783 = 8740844
163 + 8740681 = 8740844
241 + 8740603 = 8740844
283 + 8740561 = 8740844
313 + 8740531 = 8740844
397 + 8740447 = 8740844

Showing the first eight; more decompositions exist.
