Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552254, here are decompositions:

17 + 31552237 = 31552254
43 + 31552211 = 31552254
47 + 31552207 = 31552254
61 + 31552193 = 31552254
127 + 31552127 = 31552254
197 + 31552057 = 31552254
257 + 31551997 = 31552254
277 + 31551977 = 31552254

Showing the first eight; more decompositions exist.
