Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947780, here are decompositions:

7 + 947773 = 947780
37 + 947743 = 947780
61 + 947719 = 947780
73 + 947707 = 947780
139 + 947641 = 947780
241 + 947539 = 947780
271 + 947509 = 947780
331 + 947449 = 947780

Showing the first eight; more decompositions exist.
