Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541664, here are decompositions:

3 + 541661 = 541664
7 + 541657 = 541664
127 + 541537 = 541664
157 + 541507 = 541664
181 + 541483 = 541664
283 + 541381 = 541664
397 + 541267 = 541664
433 + 541231 = 541664

Showing the first eight; more decompositions exist.
