Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101180, here are decompositions:

7 + 101173 = 101180
19 + 101161 = 101180
31 + 101149 = 101180
61 + 101119 = 101180
67 + 101113 = 101180
73 + 101107 = 101180
181 + 100999 = 101180
193 + 100987 = 101180

Showing the first eight; more decompositions exist.
