Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947772, here are decompositions:

19 + 947753 = 947772
29 + 947743 = 947772
31 + 947741 = 947772
43 + 947729 = 947772
53 + 947719 = 947772
61 + 947711 = 947772
113 + 947659 = 947772
131 + 947641 = 947772

Showing the first eight; more decompositions exist.
