Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527426, here are decompositions:

13 + 31527413 = 31527426
19 + 31527407 = 31527426
37 + 31527389 = 31527426
83 + 31527343 = 31527426
103 + 31527323 = 31527426
109 + 31527317 = 31527426
149 + 31527277 = 31527426
173 + 31527253 = 31527426

Showing the first eight; more decompositions exist.

IPv4 address
