Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498554, here are decompositions:

5 + 31498549 = 31498554
7 + 31498547 = 31498554
13 + 31498541 = 31498554
37 + 31498517 = 31498554
41 + 31498513 = 31498554
83 + 31498471 = 31498554
127 + 31498427 = 31498554
211 + 31498343 = 31498554

Showing the first eight; more decompositions exist.
