Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180396, here are decompositions:

5 + 180391 = 180396
17 + 180379 = 180396
59 + 180337 = 180396
79 + 180317 = 180396
89 + 180307 = 180396
107 + 180289 = 180396
109 + 180287 = 180396
137 + 180259 = 180396

Showing the first eight; more decompositions exist.
