Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70730, here are decompositions:
- 13 + 70717 = 70730
- 43 + 70687 = 70730
- 67 + 70663 = 70730
- 73 + 70657 = 70730
- 103 + 70627 = 70730
- 109 + 70621 = 70730
- 157 + 70573 = 70730
- 181 + 70549 = 70730
Showing the first eight; more decompositions exist.
