Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162750, here are decompositions:
- 11 + 162739 = 162750
- 19 + 162731 = 162750
- 23 + 162727 = 162750
- 37 + 162713 = 162750
- 41 + 162709 = 162750
- 47 + 162703 = 162750
- 59 + 162691 = 162750
- 67 + 162683 = 162750
Showing the first eight; more decompositions exist.
