Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80140, here are decompositions:

29 + 80111 = 80140
89 + 80051 = 80140
101 + 80039 = 80140
167 + 79973 = 80140
173 + 79967 = 80140
197 + 79943 = 80140
233 + 79907 = 80140
239 + 79901 = 80140

Showing the first eight; more decompositions exist.
