Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 945172, here are decompositions:

29 + 945143 = 945172
83 + 945089 = 945172
113 + 945059 = 945172
443 + 944729 = 945172
461 + 944711 = 945172
521 + 944651 = 945172
563 + 944609 = 945172
593 + 944579 = 945172

Showing the first eight; more decompositions exist.
