Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492532, here are decompositions:

5 + 2147492527 = 2147492532
11 + 2147492521 = 2147492532
41 + 2147492491 = 2147492532
43 + 2147492489 = 2147492532
103 + 2147492429 = 2147492532
139 + 2147492393 = 2147492532
179 + 2147492353 = 2147492532
193 + 2147492339 = 2147492532

Showing the first eight; more decompositions exist.

IPv4 address
