Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536420, here are decompositions:

17 + 31536403 = 31536420
23 + 31536397 = 31536420
29 + 31536391 = 31536420
37 + 31536383 = 31536420
59 + 31536361 = 31536420
61 + 31536359 = 31536420
67 + 31536353 = 31536420
73 + 31536347 = 31536420

Showing the first eight; more decompositions exist.

IPv4 address
