Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180292, here are decompositions:

3 + 180289 = 180292
5 + 180287 = 180292
11 + 180281 = 180292
29 + 180263 = 180292
53 + 180239 = 180292
59 + 180233 = 180292
71 + 180221 = 180292
113 + 180179 = 180292

Showing the first eight; more decompositions exist.
