Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137884, here are decompositions:
- 11 + 137873 = 137884
- 17 + 137867 = 137884
- 53 + 137831 = 137884
- 107 + 137777 = 137884
- 113 + 137771 = 137884
- 251 + 137633 = 137884
- 311 + 137573 = 137884
- 317 + 137567 = 137884
Showing the first eight; more decompositions exist.
