Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149662, here are decompositions:
- 59 + 149603 = 149662
- 83 + 149579 = 149662
- 101 + 149561 = 149662
- 131 + 149531 = 149662
- 173 + 149489 = 149662
- 239 + 149423 = 149662
- 251 + 149411 = 149662
- 263 + 149399 = 149662
Showing the first eight; more decompositions exist.
