Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530594, here are decompositions:

5 + 31530589 = 31530594
23 + 31530571 = 31530594
71 + 31530523 = 31530594
97 + 31530497 = 31530594
107 + 31530487 = 31530594
157 + 31530437 = 31530594
211 + 31530383 = 31530594
283 + 31530311 = 31530594

Showing the first eight; more decompositions exist.

IPv4 address
