Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541390, here are decompositions:

29 + 541361 = 541390
41 + 541349 = 541390
89 + 541301 = 541390
107 + 541283 = 541390
173 + 541217 = 541390
197 + 541193 = 541390
257 + 541133 = 541390
293 + 541097 = 541390

Showing the first eight; more decompositions exist.
