Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 477842, here are decompositions:

3 + 477839 = 477842
19 + 477823 = 477842
31 + 477811 = 477842
73 + 477769 = 477842
103 + 477739 = 477842
223 + 477619 = 477842
271 + 477571 = 477842
331 + 477511 = 477842

Showing the first eight; more decompositions exist.
