Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1508, here are decompositions:
- 19 + 1489 = 1508
- 37 + 1471 = 1508
- 61 + 1447 = 1508
- 79 + 1429 = 1508
- 109 + 1399 = 1508
- 127 + 1381 = 1508
- 181 + 1327 = 1508
- 211 + 1297 = 1508
Showing the first eight; more decompositions exist.
