Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947782, here are decompositions:

29 + 947753 = 947782
41 + 947741 = 947782
53 + 947729 = 947782
71 + 947711 = 947782
131 + 947651 = 947782
179 + 947603 = 947782
281 + 947501 = 947782
359 + 947423 = 947782

Showing the first eight; more decompositions exist.
