Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498822, here are decompositions:

11 + 31498811 = 31498822
59 + 31498763 = 31498822
263 + 31498559 = 31498822
281 + 31498541 = 31498822
293 + 31498529 = 31498822
353 + 31498469 = 31498822
359 + 31498463 = 31498822
401 + 31498421 = 31498822

Showing the first eight; more decompositions exist.
