Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493486, here are decompositions:

7 + 2147493479 = 2147493486
29 + 2147493457 = 2147493486
53 + 2147493433 = 2147493486
197 + 2147493289 = 2147493486
317 + 2147493169 = 2147493486
367 + 2147493119 = 2147493486
409 + 2147493077 = 2147493486
433 + 2147493053 = 2147493486

Showing the first eight; more decompositions exist.

IPv4 address
