Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552576, here are decompositions:

23 + 31552553 = 31552576
89 + 31552487 = 31552576
173 + 31552403 = 31552576
347 + 31552229 = 31552576
383 + 31552193 = 31552576
449 + 31552127 = 31552576
557 + 31552019 = 31552576
599 + 31551977 = 31552576

Showing the first eight; more decompositions exist.
