Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479256, here are decompositions:

5 + 31479251 = 31479256
59 + 31479197 = 31479256
173 + 31479083 = 31479256
239 + 31479017 = 31479256
449 + 31478807 = 31479256
617 + 31478639 = 31479256
773 + 31478483 = 31479256
827 + 31478429 = 31479256

Showing the first eight; more decompositions exist.
