Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149126, here are decompositions:
- 7 + 149119 = 149126
- 13 + 149113 = 149126
- 67 + 149059 = 149126
- 73 + 149053 = 149126
- 193 + 148933 = 149126
- 199 + 148927 = 149126
- 379 + 148747 = 149126
- 433 + 148693 = 149126
Showing the first eight; more decompositions exist.
