Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535078, here are decompositions:

19 + 31535059 = 31535078
67 + 31535011 = 31535078
79 + 31534999 = 31535078
97 + 31534981 = 31535078
199 + 31534879 = 31535078
277 + 31534801 = 31535078
349 + 31534729 = 31535078
409 + 31534669 = 31535078

Showing the first eight; more decompositions exist.

IPv4 address
