Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180982, here are decompositions:

23 + 180959 = 180982
233 + 180749 = 180982
251 + 180731 = 180982
281 + 180701 = 180982
353 + 180629 = 180982
359 + 180623 = 180982
419 + 180563 = 180982
443 + 180539 = 180982

Showing the first eight; more decompositions exist.
