Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474254, here are decompositions:

5 + 31474249 = 31474254
37 + 31474217 = 31474254
41 + 31474213 = 31474254
83 + 31474171 = 31474254
113 + 31474141 = 31474254
181 + 31474073 = 31474254
193 + 31474061 = 31474254
197 + 31474057 = 31474254

Showing the first eight; more decompositions exist.
