Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562926, here are decompositions:

149 + 31562777 = 31562926
359 + 31562567 = 31562926
383 + 31562543 = 31562926
443 + 31562483 = 31562926
503 + 31562423 = 31562926
569 + 31562357 = 31562926
653 + 31562273 = 31562926
683 + 31562243 = 31562926

Showing the first eight; more decompositions exist.
