Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945042, here are decompositions:

5 + 945037 = 945042
11 + 945031 = 945042
73 + 944969 = 945042
79 + 944963 = 945042
89 + 944953 = 945042
113 + 944929 = 945042
149 + 944893 = 945042
239 + 944803 = 945042

Showing the first eight; more decompositions exist.
