Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155304, here are decompositions:

5 + 155299 = 155304
13 + 155291 = 155304
53 + 155251 = 155304
73 + 155231 = 155304
101 + 155203 = 155304
103 + 155201 = 155304
113 + 155191 = 155304
137 + 155167 = 155304

Showing the first eight; more decompositions exist.
