Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443898, here are decompositions:
- 109 + 2147443789 = 2147443898
- 139 + 2147443759 = 2147443898
- 151 + 2147443747 = 2147443898
- 331 + 2147443567 = 2147443898
- 337 + 2147443561 = 2147443898
- 487 + 2147443411 = 2147443898
- 499 + 2147443399 = 2147443898
- 541 + 2147443357 = 2147443898
Showing the first eight; more decompositions exist.
