Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742404, here are decompositions:

3 + 8742401 = 8742404
37 + 8742367 = 8742404
211 + 8742193 = 8742404
271 + 8742133 = 8742404
283 + 8742121 = 8742404
337 + 8742067 = 8742404
367 + 8742037 = 8742404
421 + 8741983 = 8742404

Showing the first eight; more decompositions exist.
