Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491360, here are decompositions:
- 3 + 491357 = 491360
- 7 + 491353 = 491360
- 19 + 491341 = 491360
- 31 + 491329 = 491360
- 61 + 491299 = 491360
- 109 + 491251 = 491360
- 193 + 491167 = 491360
- 211 + 491149 = 491360
Showing the first eight; more decompositions exist.
