Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562726, here are decompositions:

43 + 31562683 = 31562726
103 + 31562623 = 31562726
109 + 31562617 = 31562726
277 + 31562449 = 31562726
337 + 31562389 = 31562726
379 + 31562347 = 31562726
397 + 31562329 = 31562726
463 + 31562263 = 31562726

Showing the first eight; more decompositions exist.
