Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180794, here are decompositions:

43 + 180751 = 180794
127 + 180667 = 180794
283 + 180511 = 180794
331 + 180463 = 180794
433 + 180361 = 180794
457 + 180337 = 180794
463 + 180331 = 180794
487 + 180307 = 180794

Showing the first eight; more decompositions exist.
