Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534082, here are decompositions:

3 + 31534079 = 31534082
31 + 31534051 = 31534082
103 + 31533979 = 31534082
163 + 31533919 = 31534082
211 + 31533871 = 31534082
313 + 31533769 = 31534082
421 + 31533661 = 31534082
571 + 31533511 = 31534082

Showing the first eight; more decompositions exist.

IPv4 address
