Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558452, here are decompositions:

19 + 31558433 = 31558452
53 + 31558399 = 31558452
61 + 31558391 = 31558452
71 + 31558381 = 31558452
73 + 31558379 = 31558452
131 + 31558321 = 31558452
199 + 31558253 = 31558452
223 + 31558229 = 31558452

Showing the first eight; more decompositions exist.
