Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1430, here are decompositions:
- 3 + 1427 = 1430
- 7 + 1423 = 1430
- 31 + 1399 = 1430
- 103 + 1327 = 1430
- 109 + 1321 = 1430
- 127 + 1303 = 1430
- 139 + 1291 = 1430
- 151 + 1279 = 1430
Showing the first eight; more decompositions exist.
