Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496408, here are decompositions:

19 + 31496389 = 31496408
37 + 31496371 = 31496408
79 + 31496329 = 31496408
199 + 31496209 = 31496408
367 + 31496041 = 31496408
397 + 31496011 = 31496408
487 + 31495921 = 31496408
607 + 31495801 = 31496408

Showing the first eight; more decompositions exist.
