Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109880, here are decompositions:

7 + 109873 = 109880
31 + 109849 = 109880
37 + 109843 = 109880
61 + 109819 = 109880
73 + 109807 = 109880
139 + 109741 = 109880
163 + 109717 = 109880
241 + 109639 = 109880

Showing the first eight; more decompositions exist.
