Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945148, here are decompositions:

5 + 945143 = 945148
59 + 945089 = 945148
89 + 945059 = 945148
179 + 944969 = 945148
251 + 944897 = 945148
419 + 944729 = 945148
431 + 944717 = 945148
461 + 944687 = 945148

Showing the first eight; more decompositions exist.
