Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80042, here are decompositions:

3 + 80039 = 80042
43 + 79999 = 80042
103 + 79939 = 80042
139 + 79903 = 80042
181 + 79861 = 80042
199 + 79843 = 80042
229 + 79813 = 80042
241 + 79801 = 80042

Showing the first eight; more decompositions exist.
