Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947472, here are decompositions:

23 + 947449 = 947472
41 + 947431 = 947472
59 + 947413 = 947472
61 + 947411 = 947472
83 + 947389 = 947472
89 + 947383 = 947472
103 + 947369 = 947472
131 + 947341 = 947472

Showing the first eight; more decompositions exist.
