Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572142, here are decompositions:

5 + 572137 = 572142
73 + 572069 = 572142
79 + 572063 = 572142
83 + 572059 = 572142
89 + 572053 = 572142
101 + 572041 = 572142
173 + 571969 = 572142
239 + 571903 = 572142

Showing the first eight; more decompositions exist.
