Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499274, here are decompositions:

7 + 31499267 = 31499274
43 + 31499231 = 31499274
47 + 31499227 = 31499274
113 + 31499161 = 31499274
137 + 31499137 = 31499274
167 + 31499107 = 31499274
197 + 31499077 = 31499274
211 + 31499063 = 31499274

Showing the first eight; more decompositions exist.
