Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541242, here are decompositions:

5 + 541237 = 541242
11 + 541231 = 541242
41 + 541201 = 541242
61 + 541181 = 541242
89 + 541153 = 541242
101 + 541141 = 541242
109 + 541133 = 541242
113 + 541129 = 541242

Showing the first eight; more decompositions exist.
