Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157672, here are decompositions:
- 3 + 157669 = 157672
- 5 + 157667 = 157672
- 23 + 157649 = 157672
- 101 + 157571 = 157672
- 113 + 157559 = 157672
- 149 + 157523 = 157672
- 239 + 157433 = 157672
- 401 + 157271 = 157672
Showing the first eight; more decompositions exist.
