Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019442, here are decompositions:
- 19 + 1019423 = 1019442
- 29 + 1019413 = 1019442
- 31 + 1019411 = 1019442
- 43 + 1019399 = 1019442
- 89 + 1019353 = 1019442
- 103 + 1019339 = 1019442
- 113 + 1019329 = 1019442
- 181 + 1019261 = 1019442
Showing the first eight; more decompositions exist.
