Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148646, here are decompositions:
- 7 + 148639 = 148646
- 13 + 148633 = 148646
- 19 + 148627 = 148646
- 37 + 148609 = 148646
- 67 + 148579 = 148646
- 73 + 148573 = 148646
- 97 + 148549 = 148646
- 109 + 148537 = 148646
Showing the first eight; more decompositions exist.
