Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541438, here are decompositions:

47 + 541391 = 541438
89 + 541349 = 541438
137 + 541301 = 541438
167 + 541271 = 541438
257 + 541181 = 541438
389 + 541049 = 541438
431 + 541007 = 541438
449 + 540989 = 541438

Showing the first eight; more decompositions exist.
