Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137998, here are decompositions:
- 5 + 137993 = 137998
- 41 + 137957 = 137998
- 71 + 137927 = 137998
- 89 + 137909 = 137998
- 131 + 137867 = 137998
- 149 + 137849 = 137998
- 167 + 137831 = 137998
- 227 + 137771 = 137998
Showing the first eight; more decompositions exist.
