Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146970, here are decompositions:
- 17 + 146953 = 146970
- 29 + 146941 = 146970
- 37 + 146933 = 146970
- 53 + 146917 = 146970
- 79 + 146891 = 146970
- 113 + 146857 = 146970
- 127 + 146843 = 146970
- 137 + 146833 = 146970
Showing the first eight; more decompositions exist.
