Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80242, here are decompositions:

3 + 80239 = 80242
11 + 80231 = 80242
89 + 80153 = 80242
101 + 80141 = 80242
131 + 80111 = 80242
191 + 80051 = 80242
263 + 79979 = 80242
269 + 79973 = 80242

Showing the first eight; more decompositions exist.
