Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552074, here are decompositions:

5 + 31552069 = 31552074
17 + 31552057 = 31552074
41 + 31552033 = 31552074
97 + 31551977 = 31552074
137 + 31551937 = 31552074
173 + 31551901 = 31552074
271 + 31551803 = 31552074
293 + 31551781 = 31552074

Showing the first eight; more decompositions exist.
