Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180944, here are decompositions:

37 + 180907 = 180944
61 + 180883 = 180944
73 + 180871 = 180944
97 + 180847 = 180944
151 + 180793 = 180944
193 + 180751 = 180944
277 + 180667 = 180944
397 + 180547 = 180944

Showing the first eight; more decompositions exist.
