Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145598, here are decompositions:
- 67 + 145531 = 145598
- 97 + 145501 = 145598
- 127 + 145471 = 145598
- 139 + 145459 = 145598
- 157 + 145441 = 145598
- 181 + 145417 = 145598
- 199 + 145399 = 145598
- 331 + 145267 = 145598
Showing the first eight; more decompositions exist.
