Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542236, here are decompositions:

17 + 542219 = 542236
29 + 542207 = 542236
47 + 542189 = 542236
53 + 542183 = 542236
83 + 542153 = 542236
113 + 542123 = 542236
173 + 542063 = 542236
269 + 541967 = 542236

Showing the first eight; more decompositions exist.
