Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552100, here are decompositions:

31 + 31552069 = 31552100
43 + 31552057 = 31552100
67 + 31552033 = 31552100
103 + 31551997 = 31552100
163 + 31551937 = 31552100
199 + 31551901 = 31552100
241 + 31551859 = 31552100
367 + 31551733 = 31552100

Showing the first eight; more decompositions exist.
