Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27042, here are decompositions:

11 + 27031 = 27042
31 + 27011 = 27042
61 + 26981 = 27042
83 + 26959 = 27042
89 + 26953 = 27042
139 + 26903 = 27042
149 + 26893 = 27042
151 + 26891 = 27042

Showing the first eight; more decompositions exist.
