Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147457272, here are decompositions:
- 13 + 2147457259 = 2147457272
- 31 + 2147457241 = 2147457272
- 43 + 2147457229 = 2147457272
- 61 + 2147457211 = 2147457272
- 73 + 2147457199 = 2147457272
- 199 + 2147457073 = 2147457272
- 211 + 2147457061 = 2147457272
- 223 + 2147457049 = 2147457272
Showing the first eight; more decompositions exist.
