Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741242, here are decompositions:

11 + 8741231 = 8741242
89 + 8741153 = 8741242
101 + 8741141 = 8741242
113 + 8741129 = 8741242
383 + 8740859 = 8741242
401 + 8740841 = 8741242
443 + 8740799 = 8741242
449 + 8740793 = 8741242

Showing the first eight; more decompositions exist.
