Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498954, here are decompositions:

5 + 31498949 = 31498954
23 + 31498931 = 31498954
41 + 31498913 = 31498954
101 + 31498853 = 31498954
107 + 31498847 = 31498954
191 + 31498763 = 31498954
251 + 31498703 = 31498954
491 + 31498463 = 31498954

Showing the first eight; more decompositions exist.
