Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157930, here are decompositions:
- 23 + 157907 = 157930
- 29 + 157901 = 157930
- 41 + 157889 = 157930
- 53 + 157877 = 157930
- 89 + 157841 = 157930
- 107 + 157823 = 157930
- 131 + 157799 = 157930
- 137 + 157793 = 157930
Showing the first eight; more decompositions exist.
