Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143690, here are decompositions:
- 3 + 143687 = 143690
- 13 + 143677 = 143690
- 37 + 143653 = 143690
- 61 + 143629 = 143690
- 73 + 143617 = 143690
- 97 + 143593 = 143690
- 139 + 143551 = 143690
- 163 + 143527 = 143690
Showing the first eight; more decompositions exist.
