Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474230, here are decompositions:

13 + 31474217 = 31474230
17 + 31474213 = 31474230
59 + 31474171 = 31474230
89 + 31474141 = 31474230
101 + 31474129 = 31474230
157 + 31474073 = 31474230
173 + 31474057 = 31474230
197 + 31474033 = 31474230

Showing the first eight; more decompositions exist.
