Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127880, here are decompositions:

3 + 127877 = 127880
7 + 127873 = 127880
13 + 127867 = 127880
31 + 127849 = 127880
37 + 127843 = 127880
43 + 127837 = 127880
61 + 127819 = 127880
73 + 127807 = 127880

Showing the first eight; more decompositions exist.
