Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66260, here are decompositions:

151 + 66109 = 66260
157 + 66103 = 66260
193 + 66067 = 66260
223 + 66037 = 66260
277 + 65983 = 66260
331 + 65929 = 66260
379 + 65881 = 66260
409 + 65851 = 66260

Showing the first eight; more decompositions exist.
