Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498464, here are decompositions:

37 + 31498427 = 31498464
43 + 31498421 = 31498464
97 + 31498367 = 31498464
157 + 31498307 = 31498464
191 + 31498273 = 31498464
211 + 31498253 = 31498464
251 + 31498213 = 31498464
271 + 31498193 = 31498464

Showing the first eight; more decompositions exist.
