Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157586, here are decompositions:
- 7 + 157579 = 157586
- 43 + 157543 = 157586
- 67 + 157519 = 157586
- 73 + 157513 = 157586
- 97 + 157489 = 157586
- 103 + 157483 = 157586
- 109 + 157477 = 157586
- 157 + 157429 = 157586
Showing the first eight; more decompositions exist.
