Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582554, here are decompositions:

7 + 31582547 = 31582554
23 + 31582531 = 31582554
41 + 31582513 = 31582554
83 + 31582471 = 31582554
137 + 31582417 = 31582554
151 + 31582403 = 31582554
233 + 31582321 = 31582554
313 + 31582241 = 31582554

Showing the first eight; more decompositions exist.
