Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987260, here are decompositions:

61 + 987199 = 987260
67 + 987193 = 987260
163 + 987097 = 987260
181 + 987079 = 987260
193 + 987067 = 987260
199 + 987061 = 987260
271 + 986989 = 987260
277 + 986983 = 987260

Showing the first eight; more decompositions exist.
