Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 972146, here are decompositions:

13 + 972133 = 972146
67 + 972079 = 972146
157 + 971989 = 972146
229 + 971917 = 972146
283 + 971863 = 972146
313 + 971833 = 972146
379 + 971767 = 972146
433 + 971713 = 972146

Showing the first eight; more decompositions exist.
