Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541402, here are decompositions:

3 + 31541399 = 31541402
43 + 31541359 = 31541402
223 + 31541179 = 31541402
229 + 31541173 = 31541402
241 + 31541161 = 31541402
331 + 31541071 = 31541402
463 + 31540939 = 31541402
619 + 31540783 = 31541402

Showing the first eight; more decompositions exist.

IPv4 address
