Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472146, here are decompositions:

7 + 472139 = 472146
13 + 472133 = 472146
19 + 472127 = 472146
23 + 472123 = 472146
43 + 472103 = 472146
79 + 472067 = 472146
83 + 472063 = 472146
89 + 472057 = 472146

Showing the first eight; more decompositions exist.
