Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562552, here are decompositions:

103 + 31562449 = 31562552
163 + 31562389 = 31562552
223 + 31562329 = 31562552
271 + 31562281 = 31562552
433 + 31562119 = 31562552
499 + 31562053 = 31562552
613 + 31561939 = 31562552
751 + 31561801 = 31562552

Showing the first eight; more decompositions exist.
