Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540904, here are decompositions:

3 + 540901 = 540904
41 + 540863 = 540904
53 + 540851 = 540904
101 + 540803 = 540904
131 + 540773 = 540904
191 + 540713 = 540904
227 + 540677 = 540904
293 + 540611 = 540904

Showing the first eight; more decompositions exist.
