Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531494, here are decompositions:

13 + 531481 = 531494
37 + 531457 = 531494
151 + 531343 = 531494
157 + 531337 = 531494
163 + 531331 = 531494
241 + 531253 = 531494
331 + 531163 = 531494
373 + 531121 = 531494

Showing the first eight; more decompositions exist.
