Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181952, here are decompositions:

61 + 181891 = 181952
79 + 181873 = 181952
139 + 181813 = 181952
163 + 181789 = 181952
193 + 181759 = 181952
223 + 181729 = 181952
241 + 181711 = 181952
283 + 181669 = 181952

Showing the first eight; more decompositions exist.
