Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496100, here are decompositions:

17 + 31496083 = 31496100
43 + 31496057 = 31496100
59 + 31496041 = 31496100
73 + 31496027 = 31496100
89 + 31496011 = 31496100
151 + 31495949 = 31496100
179 + 31495921 = 31496100
241 + 31495859 = 31496100

Showing the first eight; more decompositions exist.
