Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552130, here are decompositions:

3 + 31552127 = 31552130
61 + 31552069 = 31552130
73 + 31552057 = 31552130
97 + 31552033 = 31552130
151 + 31551979 = 31552130
193 + 31551937 = 31552130
229 + 31551901 = 31552130
271 + 31551859 = 31552130

Showing the first eight; more decompositions exist.
