Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152390, here are decompositions:

13 + 152377 = 152390
79 + 152311 = 152390
97 + 152293 = 152390
103 + 152287 = 152390
151 + 152239 = 152390
193 + 152197 = 152390
307 + 152083 = 152390
313 + 152077 = 152390

Showing the first eight; more decompositions exist.
