Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472328, here are decompositions:

37 + 31472291 = 31472328
67 + 31472261 = 31472328
89 + 31472239 = 31472328
127 + 31472201 = 31472328
137 + 31472191 = 31472328
149 + 31472179 = 31472328
179 + 31472149 = 31472328
197 + 31472131 = 31472328

Showing the first eight; more decompositions exist.
