Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498828, here are decompositions:

17 + 31498811 = 31498828
269 + 31498559 = 31498828
281 + 31498547 = 31498828
311 + 31498517 = 31498828
359 + 31498469 = 31498828
401 + 31498427 = 31498828
461 + 31498367 = 31498828
479 + 31498349 = 31498828

Showing the first eight; more decompositions exist.
