Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945100, here are decompositions:

11 + 945089 = 945100
41 + 945059 = 945100
113 + 944987 = 945100
131 + 944969 = 945100
137 + 944963 = 945100
227 + 944873 = 945100
383 + 944717 = 945100
389 + 944711 = 945100

Showing the first eight; more decompositions exist.
