Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528442, here are decompositions:
- 79 + 31528363 = 31528442
- 151 + 31528291 = 31528442
- 163 + 31528279 = 31528442
- 229 + 31528213 = 31528442
- 271 + 31528171 = 31528442
- 331 + 31528111 = 31528442
- 349 + 31528093 = 31528442
- 373 + 31528069 = 31528442
Showing the first eight; more decompositions exist.
