Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741842, here are decompositions:

3 + 8741839 = 8741842
29 + 8741813 = 8741842
41 + 8741801 = 8741842
89 + 8741753 = 8741842
101 + 8741741 = 8741842
233 + 8741609 = 8741842
383 + 8741459 = 8741842
449 + 8741393 = 8741842

Showing the first eight; more decompositions exist.
