Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541640, here are decompositions:

61 + 541579 = 541640
97 + 541543 = 541640
103 + 541537 = 541640
109 + 541531 = 541640
157 + 541483 = 541640
193 + 541447 = 541640
223 + 541417 = 541640
271 + 541369 = 541640

Showing the first eight; more decompositions exist.
