Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180698, here are decompositions:

19 + 180679 = 180698
31 + 180667 = 180698
151 + 180547 = 180698
157 + 180541 = 180698
307 + 180391 = 180698
337 + 180361 = 180698
367 + 180331 = 180698
409 + 180289 = 180698

Showing the first eight; more decompositions exist.
