Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496678, here are decompositions:

7 + 31496671 = 31496678
67 + 31496611 = 31496678
79 + 31496599 = 31496678
127 + 31496551 = 31496678
139 + 31496539 = 31496678
229 + 31496449 = 31496678
307 + 31496371 = 31496678
349 + 31496329 = 31496678

Showing the first eight; more decompositions exist.
