Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158472, here are decompositions:
- 23 + 158449 = 158472
- 29 + 158443 = 158472
- 43 + 158429 = 158472
- 53 + 158419 = 158472
- 79 + 158393 = 158472
- 101 + 158371 = 158472
- 109 + 158363 = 158472
- 113 + 158359 = 158472
Showing the first eight; more decompositions exist.
