Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562464, here are decompositions:

23 + 31562441 = 31562464
41 + 31562423 = 31562464
107 + 31562357 = 31562464
173 + 31562291 = 31562464
191 + 31562273 = 31562464
233 + 31562231 = 31562464
251 + 31562213 = 31562464
347 + 31562117 = 31562464

Showing the first eight; more decompositions exist.
