Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541842, here are decompositions:

5 + 541837 = 541842
11 + 541831 = 541842
43 + 541799 = 541842
61 + 541781 = 541842
71 + 541771 = 541842
79 + 541763 = 541842
83 + 541759 = 541842
131 + 541711 = 541842

Showing the first eight; more decompositions exist.
