Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945212, here are decompositions:

3 + 945209 = 945212
61 + 945151 = 945212
109 + 945103 = 945212
181 + 945031 = 945212
283 + 944929 = 945212
313 + 944899 = 945212
379 + 944833 = 945212
409 + 944803 = 945212

Showing the first eight; more decompositions exist.
