Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533148, here are decompositions:

5 + 31533143 = 31533148
29 + 31533119 = 31533148
47 + 31533101 = 31533148
149 + 31532999 = 31533148
167 + 31532981 = 31533148
281 + 31532867 = 31533148
461 + 31532687 = 31533148
509 + 31532639 = 31533148

Showing the first eight; more decompositions exist.

IPv4 address
