Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562254, here are decompositions:

11 + 31562243 = 31562254
23 + 31562231 = 31562254
41 + 31562213 = 31562254
137 + 31562117 = 31562254
197 + 31562057 = 31562254
281 + 31561973 = 31562254
431 + 31561823 = 31562254
443 + 31561811 = 31562254

Showing the first eight; more decompositions exist.
