Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65042, here are decompositions:
- 13 + 65029 = 65042
- 31 + 65011 = 65042
- 73 + 64969 = 65042
- 151 + 64891 = 65042
- 163 + 64879 = 65042
- 193 + 64849 = 65042
- 349 + 64693 = 65042
- 379 + 64663 = 65042
Showing the first eight; more decompositions exist.
