Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66290, here are decompositions:

19 + 66271 = 66290
181 + 66109 = 66290
223 + 66067 = 66290
307 + 65983 = 66290
409 + 65881 = 66290
439 + 65851 = 66290
463 + 65827 = 66290
571 + 65719 = 66290

Showing the first eight; more decompositions exist.
