Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563254, here are decompositions:

61 + 31563193 = 31563254
67 + 31563187 = 31563254
127 + 31563127 = 31563254
181 + 31563073 = 31563254
211 + 31563043 = 31563254
223 + 31563031 = 31563254
241 + 31563013 = 31563254
271 + 31562983 = 31563254

Showing the first eight; more decompositions exist.
