Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741442, here are decompositions:

5 + 8741437 = 8741442
11 + 8741431 = 8741442
41 + 8741401 = 8741442
71 + 8741371 = 8741442
79 + 8741363 = 8741442
89 + 8741353 = 8741442
113 + 8741329 = 8741442
139 + 8741303 = 8741442

Showing the first eight; more decompositions exist.
