Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558582, here are decompositions:

53 + 31558529 = 31558582
113 + 31558469 = 31558582
149 + 31558433 = 31558582
191 + 31558391 = 31558582
353 + 31558229 = 31558582
359 + 31558223 = 31558582
383 + 31558199 = 31558582
401 + 31558181 = 31558582

Showing the first eight; more decompositions exist.
