Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71130, here are decompositions:

11 + 71119 = 71130
41 + 71089 = 71130
61 + 71069 = 71130
71 + 71059 = 71130
107 + 71023 = 71130
131 + 70999 = 71130
139 + 70991 = 71130
149 + 70981 = 71130

Showing the first eight; more decompositions exist.
