Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562692, here are decompositions:

71 + 31562621 = 31562692
89 + 31562603 = 31562692
149 + 31562543 = 31562692
173 + 31562519 = 31562692
191 + 31562501 = 31562692
251 + 31562441 = 31562692
263 + 31562429 = 31562692
269 + 31562423 = 31562692

Showing the first eight; more decompositions exist.
