Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535382, here are decompositions:

5 + 31535377 = 31535382
41 + 31535341 = 31535382
61 + 31535321 = 31535382
71 + 31535311 = 31535382
149 + 31535233 = 31535382
163 + 31535219 = 31535382
199 + 31535183 = 31535382
211 + 31535171 = 31535382

Showing the first eight; more decompositions exist.

IPv4 address
