Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562754, here are decompositions:

17 + 31562737 = 31562754
43 + 31562711 = 31562754
71 + 31562683 = 31562754
127 + 31562627 = 31562754
131 + 31562623 = 31562754
137 + 31562617 = 31562754
151 + 31562603 = 31562754
211 + 31562543 = 31562754

Showing the first eight; more decompositions exist.
