Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71242, here are decompositions:

5 + 71237 = 71242
71 + 71171 = 71242
89 + 71153 = 71242
113 + 71129 = 71242
173 + 71069 = 71242
251 + 70991 = 71242
263 + 70979 = 71242
293 + 70949 = 71242

Showing the first eight; more decompositions exist.
