Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541142, here are decompositions:

13 + 541129 = 541142
181 + 540961 = 541142
241 + 540901 = 541142
271 + 540871 = 541142
373 + 540769 = 541142
439 + 540703 = 541142
463 + 540679 = 541142
523 + 540619 = 541142

Showing the first eight; more decompositions exist.
