Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66020, here are decompositions:

37 + 65983 = 66020
139 + 65881 = 66020
181 + 65839 = 66020
193 + 65827 = 66020
211 + 65809 = 66020
307 + 65713 = 66020
313 + 65707 = 66020
373 + 65647 = 66020

Showing the first eight; more decompositions exist.
