Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540488, here are decompositions:

19 + 540469 = 540488
97 + 540391 = 540488
139 + 540349 = 540488
181 + 540307 = 540488
271 + 540217 = 540488
307 + 540181 = 540488
331 + 540157 = 540488
349 + 540139 = 540488

Showing the first eight; more decompositions exist.
