Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542346, here are decompositions:

5 + 31542341 = 31542346
23 + 31542323 = 31542346
113 + 31542233 = 31542346
149 + 31542197 = 31542346
197 + 31542149 = 31542346
233 + 31542113 = 31542346
263 + 31542083 = 31542346
443 + 31541903 = 31542346

Showing the first eight; more decompositions exist.

IPv4 address
