Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157626, here are decompositions:
- 47 + 157579 = 157626
- 67 + 157559 = 157626
- 83 + 157543 = 157626
- 103 + 157523 = 157626
- 107 + 157519 = 157626
- 113 + 157513 = 157626
- 137 + 157489 = 157626
- 149 + 157477 = 157626
Showing the first eight; more decompositions exist.
