Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143648, here are decompositions:
- 19 + 143629 = 143648
- 31 + 143617 = 143648
- 79 + 143569 = 143648
- 97 + 143551 = 143648
- 139 + 143509 = 143648
- 181 + 143467 = 143648
- 229 + 143419 = 143648
- 367 + 143281 = 143648
Showing the first eight; more decompositions exist.
