Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541128, here are decompositions:

31 + 541097 = 541128
41 + 541087 = 541128
67 + 541061 = 541128
79 + 541049 = 541128
101 + 541027 = 541128
127 + 541001 = 541128
139 + 540989 = 541128
167 + 540961 = 541128

Showing the first eight; more decompositions exist.
