Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487806, here are decompositions:

3 + 2147487803 = 2147487806
7 + 2147487799 = 2147487806
103 + 2147487703 = 2147487806
157 + 2147487649 = 2147487806
199 + 2147487607 = 2147487806
397 + 2147487409 = 2147487806
433 + 2147487373 = 2147487806
463 + 2147487343 = 2147487806

Showing the first eight; more decompositions exist.

IPv4 address
