Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496884, here are decompositions:

11 + 31496873 = 31496884
101 + 31496783 = 31496884
191 + 31496693 = 31496884
311 + 31496573 = 31496884
317 + 31496567 = 31496884
347 + 31496537 = 31496884
443 + 31496441 = 31496884
467 + 31496417 = 31496884

Showing the first eight; more decompositions exist.
