Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180506, here are decompositions:

3 + 180503 = 180506
43 + 180463 = 180506
127 + 180379 = 180506
199 + 180307 = 180506
409 + 180097 = 180506
433 + 180073 = 180506
463 + 180043 = 180506
499 + 180007 = 180506

Showing the first eight; more decompositions exist.
