Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532042, here are decompositions:

229 + 31531813 = 31532042
463 + 31531579 = 31532042
571 + 31531471 = 31532042
643 + 31531399 = 31532042
673 + 31531369 = 31532042
739 + 31531303 = 31532042
769 + 31531273 = 31532042
1063 + 31530979 = 31532042

Showing the first eight; more decompositions exist.

IPv4 address
