Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540278, here are decompositions:

7 + 540271 = 540278
61 + 540217 = 540278
97 + 540181 = 540278
139 + 540139 = 540278
157 + 540121 = 540278
199 + 540079 = 540278
331 + 539947 = 540278
379 + 539899 = 540278

Showing the first eight; more decompositions exist.
