Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180752, here are decompositions:

3 + 180749 = 180752
73 + 180679 = 180752
211 + 180541 = 180752
241 + 180511 = 180752
373 + 180379 = 180752
421 + 180331 = 180752
463 + 180289 = 180752
541 + 180211 = 180752

Showing the first eight; more decompositions exist.
