Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180346, here are decompositions:

29 + 180317 = 180346
59 + 180287 = 180346
83 + 180263 = 180346
107 + 180239 = 180346
113 + 180233 = 180346
167 + 180179 = 180346
269 + 180077 = 180346
293 + 180053 = 180346

Showing the first eight; more decompositions exist.
