Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541840, here are decompositions:

3 + 541837 = 541840
23 + 541817 = 541840
41 + 541799 = 541840
59 + 541781 = 541840
113 + 541727 = 541840
179 + 541661 = 541840
227 + 541613 = 541840
251 + 541589 = 541840

Showing the first eight; more decompositions exist.
