Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483228, here are decompositions:
- 151 + 2147483077 = 2147483228
- 199 + 2147483029 = 2147483228
- 277 + 2147482951 = 2147483228
- 307 + 2147482921 = 2147483228
- 409 + 2147482819 = 2147483228
- 547 + 2147482681 = 2147483228
- 607 + 2147482621 = 2147483228
- 727 + 2147482501 = 2147483228
Showing the first eight; more decompositions exist.
