Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 540156, here are decompositions:

7 + 540149 = 540156
17 + 540139 = 540156
37 + 540119 = 540156
163 + 539993 = 540156
257 + 539899 = 540156
293 + 539863 = 540156
307 + 539849 = 540156
313 + 539843 = 540156

Showing the first eight; more decompositions exist.
