Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66248, here are decompositions:

79 + 66169 = 66248
139 + 66109 = 66248
181 + 66067 = 66248
211 + 66037 = 66248
349 + 65899 = 66248
367 + 65881 = 66248
397 + 65851 = 66248
409 + 65839 = 66248

Showing the first eight; more decompositions exist.
