Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86042, here are decompositions:

13 + 86029 = 86042
31 + 86011 = 86042
43 + 85999 = 86042
109 + 85933 = 86042
139 + 85903 = 86042
199 + 85843 = 86042
211 + 85831 = 86042
223 + 85819 = 86042

Showing the first eight; more decompositions exist.
