Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492042, here are decompositions:

13 + 2147492029 = 2147492042
19 + 2147492023 = 2147492042
139 + 2147491903 = 2147492042
211 + 2147491831 = 2147492042
433 + 2147491609 = 2147492042
439 + 2147491603 = 2147492042
499 + 2147491543 = 2147492042
673 + 2147491369 = 2147492042

Showing the first eight; more decompositions exist.

IPv4 address
