Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103940, here are decompositions:

37 + 103903 = 103940
73 + 103867 = 103940
97 + 103843 = 103940
103 + 103837 = 103940
127 + 103813 = 103940
139 + 103801 = 103940
241 + 103699 = 103940
271 + 103669 = 103940

Showing the first eight; more decompositions exist.
