Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147042, here are decompositions:
- 11 + 147031 = 147042
- 13 + 147029 = 147042
- 31 + 147011 = 147042
- 53 + 146989 = 147042
- 59 + 146983 = 147042
- 89 + 146953 = 147042
- 101 + 146941 = 147042
- 109 + 146933 = 147042
Showing the first eight; more decompositions exist.
