Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79940, here are decompositions:

37 + 79903 = 79940
67 + 79873 = 79940
73 + 79867 = 79940
79 + 79861 = 79940
97 + 79843 = 79940
127 + 79813 = 79940
139 + 79801 = 79940
163 + 79777 = 79940

Showing the first eight; more decompositions exist.
