Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143654, here are decompositions:

3 + 143651 = 143654
37 + 143617 = 143654
61 + 143593 = 143654
103 + 143551 = 143654
127 + 143527 = 143654
151 + 143503 = 143654
193 + 143461 = 143654
211 + 143443 = 143654

Showing the first eight; more decompositions exist.
