Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151628, here are decompositions:
- 19 + 151609 = 151628
- 31 + 151597 = 151628
- 67 + 151561 = 151628
- 79 + 151549 = 151628
- 97 + 151531 = 151628
- 151 + 151477 = 151628
- 157 + 151471 = 151628
- 199 + 151429 = 151628
Showing the first eight; more decompositions exist.
