Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947722, here are decompositions:

3 + 947719 = 947722
11 + 947711 = 947722
71 + 947651 = 947722
101 + 947621 = 947722
239 + 947483 = 947722
311 + 947411 = 947722
353 + 947369 = 947722
593 + 947129 = 947722

Showing the first eight; more decompositions exist.
