Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70800, here are decompositions:
- 7 + 70793 = 70800
- 17 + 70783 = 70800
- 31 + 70769 = 70800
- 47 + 70753 = 70800
- 71 + 70729 = 70800
- 83 + 70717 = 70800
- 113 + 70687 = 70800
- 137 + 70663 = 70800
Showing the first eight; more decompositions exist.
