Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487780, here are decompositions:

7 + 2147487773 = 2147487780
23 + 2147487757 = 2147487780
29 + 2147487751 = 2147487780
79 + 2147487701 = 2147487780
89 + 2147487691 = 2147487780
131 + 2147487649 = 2147487780
157 + 2147487623 = 2147487780
173 + 2147487607 = 2147487780

Showing the first eight; more decompositions exist.

IPv4 address
