Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541520, here are decompositions:

13 + 541507 = 541520
37 + 541483 = 541520
73 + 541447 = 541520
103 + 541417 = 541520
139 + 541381 = 541520
151 + 541369 = 541520
157 + 541363 = 541520
181 + 541339 = 541520

Showing the first eight; more decompositions exist.
