Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496704, here are decompositions:

11 + 31496693 = 31496704
131 + 31496573 = 31496704
137 + 31496567 = 31496704
167 + 31496537 = 31496704
263 + 31496441 = 31496704
383 + 31496321 = 31496704
443 + 31496261 = 31496704
563 + 31496141 = 31496704

Showing the first eight; more decompositions exist.
