Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534862, here are decompositions:

31 + 31534831 = 31534862
43 + 31534819 = 31534862
61 + 31534801 = 31534862
109 + 31534753 = 31534862
193 + 31534669 = 31534862
211 + 31534651 = 31534862
379 + 31534483 = 31534862
421 + 31534441 = 31534862

Showing the first eight; more decompositions exist.

IPv4 address
