Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152172, here are decompositions:

61 + 152111 = 152172
79 + 152093 = 152172
89 + 152083 = 152172
109 + 152063 = 152172
131 + 152041 = 152172
233 + 151939 = 152172
263 + 151909 = 152172
269 + 151903 = 152172

Showing the first eight; more decompositions exist.
