Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552448, here are decompositions:

19 + 31552429 = 31552448
61 + 31552387 = 31552448
97 + 31552351 = 31552448
139 + 31552309 = 31552448
211 + 31552237 = 31552448
241 + 31552207 = 31552448
379 + 31552069 = 31552448
547 + 31551901 = 31552448

Showing the first eight; more decompositions exist.
