Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562616, here are decompositions:

5 + 31562611 = 31562616
13 + 31562603 = 31562616
23 + 31562593 = 31562616
73 + 31562543 = 31562616
97 + 31562519 = 31562616
149 + 31562467 = 31562616
167 + 31562449 = 31562616
193 + 31562423 = 31562616

Showing the first eight; more decompositions exist.
