Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143604, here are decompositions:

11 + 143593 = 143604
31 + 143573 = 143604
37 + 143567 = 143604
53 + 143551 = 143604
67 + 143537 = 143604
101 + 143503 = 143604
103 + 143501 = 143604
127 + 143477 = 143604

Showing the first eight; more decompositions exist.
