Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945130, here are decompositions:

41 + 945089 = 945130
71 + 945059 = 945130
167 + 944963 = 945130
233 + 944897 = 945130
257 + 944873 = 945130
353 + 944777 = 945130
401 + 944729 = 945130
419 + 944711 = 945130

Showing the first eight; more decompositions exist.
