Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180626, here are decompositions:

3 + 180623 = 180626
79 + 180547 = 180626
163 + 180463 = 180626
337 + 180289 = 180626
367 + 180259 = 180626
379 + 180247 = 180626
619 + 180007 = 180626
673 + 179953 = 180626

Showing the first eight; more decompositions exist.
