Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562424, here are decompositions:

67 + 31562357 = 31562424
151 + 31562273 = 31562424
163 + 31562261 = 31562424
167 + 31562257 = 31562424
181 + 31562243 = 31562424
193 + 31562231 = 31562424
211 + 31562213 = 31562424
307 + 31562117 = 31562424

Showing the first eight; more decompositions exist.
