Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180702, here are decompositions:

23 + 180679 = 180702
73 + 180629 = 180702
79 + 180623 = 180702
139 + 180563 = 180702
163 + 180539 = 180702
191 + 180511 = 180702
199 + 180503 = 180702
211 + 180491 = 180702

Showing the first eight; more decompositions exist.
