Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145622, here are decompositions:
- 19 + 145603 = 145622
- 73 + 145549 = 145622
- 79 + 145543 = 145622
- 109 + 145513 = 145622
- 151 + 145471 = 145622
- 163 + 145459 = 145622
- 181 + 145441 = 145622
- 199 + 145423 = 145622
Showing the first eight; more decompositions exist.
