Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945542, here are decompositions:

61 + 945481 = 945542
79 + 945463 = 945542
151 + 945391 = 945542
193 + 945349 = 945542
211 + 945331 = 945542
331 + 945211 = 945542
439 + 945103 = 945542
613 + 944929 = 945542

Showing the first eight; more decompositions exist.
