Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180494, here are decompositions:

3 + 180491 = 180494
31 + 180463 = 180494
103 + 180391 = 180494
157 + 180337 = 180494
163 + 180331 = 180494
283 + 180211 = 180494
313 + 180181 = 180494
397 + 180097 = 180494

Showing the first eight; more decompositions exist.
