Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618286, here are decompositions:
- 97 + 31618189 = 31618286
- 223 + 31618063 = 31618286
- 229 + 31618057 = 31618286
- 283 + 31618003 = 31618286
- 397 + 31617889 = 31618286
- 409 + 31617877 = 31618286
- 433 + 31617853 = 31618286
- 523 + 31617763 = 31618286
Showing the first eight; more decompositions exist.
