Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151236, here are decompositions:

23 + 151213 = 151236
47 + 151189 = 151236
67 + 151169 = 151236
73 + 151163 = 151236
79 + 151157 = 151236
83 + 151153 = 151236
179 + 151057 = 151236
223 + 151013 = 151236

Showing the first eight; more decompositions exist.
