Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945142, here are decompositions:

53 + 945089 = 945142
83 + 945059 = 945142
173 + 944969 = 945142
179 + 944963 = 945142
269 + 944873 = 945142
431 + 944711 = 945142
491 + 944651 = 945142
521 + 944621 = 945142

Showing the first eight; more decompositions exist.
