Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541240, here are decompositions:

3 + 541237 = 541240
23 + 541217 = 541240
47 + 541193 = 541240
59 + 541181 = 541240
107 + 541133 = 541240
179 + 541061 = 541240
191 + 541049 = 541240
233 + 541007 = 541240

Showing the first eight; more decompositions exist.
