Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498048, here are decompositions:

5 + 31498043 = 31498048
41 + 31498007 = 31498048
107 + 31497941 = 31498048
251 + 31497797 = 31498048
311 + 31497737 = 31498048
347 + 31497701 = 31498048
479 + 31497569 = 31498048
521 + 31497527 = 31498048

Showing the first eight; more decompositions exist.
