Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57042, here are decompositions:

5 + 57037 = 57042
43 + 56999 = 57042
53 + 56989 = 57042
59 + 56983 = 57042
79 + 56963 = 57042
101 + 56941 = 57042
113 + 56929 = 57042
131 + 56911 = 57042

Showing the first eight; more decompositions exist.
