Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481242, here are decompositions:

11 + 481231 = 481242
31 + 481211 = 481242
43 + 481199 = 481242
61 + 481181 = 481242
71 + 481171 = 481242
89 + 481153 = 481242
101 + 481141 = 481242
109 + 481133 = 481242

Showing the first eight; more decompositions exist.
