Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71122, here are decompositions:

3 + 71119 = 71122
41 + 71081 = 71122
53 + 71069 = 71122
83 + 71039 = 71122
131 + 70991 = 71122
173 + 70949 = 71122
269 + 70853 = 71122
281 + 70841 = 71122

Showing the first eight; more decompositions exist.
