Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563026, here are decompositions:

13 + 31563013 = 31563026
43 + 31562983 = 31563026
67 + 31562959 = 31563026
109 + 31562917 = 31563026
199 + 31562827 = 31563026
349 + 31562677 = 31563026
409 + 31562617 = 31563026
433 + 31562593 = 31563026

Showing the first eight; more decompositions exist.
