Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541062, here are decompositions:

11 + 31541051 = 31541062
23 + 31541039 = 31541062
41 + 31541021 = 31541062
71 + 31540991 = 31541062
83 + 31540979 = 31541062
101 + 31540961 = 31541062
191 + 31540871 = 31541062
239 + 31540823 = 31541062

Showing the first eight; more decompositions exist.

IPv4 address
