Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562734, here are decompositions:

23 + 31562711 = 31562734
107 + 31562627 = 31562734
113 + 31562621 = 31562734
131 + 31562603 = 31562734
167 + 31562567 = 31562734
191 + 31562543 = 31562734
233 + 31562501 = 31562734
251 + 31562483 = 31562734

Showing the first eight; more decompositions exist.
