Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558552, here are decompositions:

23 + 31558529 = 31558552
83 + 31558469 = 31558552
89 + 31558463 = 31558552
173 + 31558379 = 31558552
269 + 31558283 = 31558552
353 + 31558199 = 31558552
383 + 31558169 = 31558552
419 + 31558133 = 31558552

Showing the first eight; more decompositions exist.
