Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452260, here are decompositions:

19 + 31452241 = 31452260
61 + 31452199 = 31452260
79 + 31452181 = 31452260
139 + 31452121 = 31452260
163 + 31452097 = 31452260
181 + 31452079 = 31452260
199 + 31452061 = 31452260
241 + 31452019 = 31452260

Showing the first eight; more decompositions exist.
