Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42488, here are decompositions:
- 31 + 42457 = 42488
- 37 + 42451 = 42488
- 79 + 42409 = 42488
- 97 + 42391 = 42488
- 109 + 42379 = 42488
- 139 + 42349 = 42488
- 151 + 42337 = 42488
- 157 + 42331 = 42488
Showing the first eight; more decompositions exist.
