Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485420, here are decompositions:

83 + 2147485337 = 2147485420
167 + 2147485253 = 2147485420
173 + 2147485247 = 2147485420
239 + 2147485181 = 2147485420
347 + 2147485073 = 2147485420
491 + 2147484929 = 2147485420
569 + 2147484851 = 2147485420
599 + 2147484821 = 2147485420

Showing the first eight; more decompositions exist.

IPv4 address
