Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541334, here are decompositions:

37 + 31541297 = 31541334
53 + 31541281 = 31541334
67 + 31541267 = 31541334
101 + 31541233 = 31541334
173 + 31541161 = 31541334
193 + 31541141 = 31541334
233 + 31541101 = 31541334
263 + 31541071 = 31541334

Showing the first eight; more decompositions exist.

IPv4 address
