Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100772, here are decompositions:

3 + 100769 = 100772
31 + 100741 = 100772
73 + 100699 = 100772
79 + 100693 = 100772
103 + 100669 = 100772
151 + 100621 = 100772
163 + 100609 = 100772
181 + 100591 = 100772

Showing the first eight; more decompositions exist.
