Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156624, here are decompositions:

5 + 156619 = 156624
23 + 156601 = 156624
31 + 156593 = 156624
47 + 156577 = 156624
103 + 156521 = 156624
113 + 156511 = 156624
131 + 156493 = 156624
137 + 156487 = 156624

Showing the first eight; more decompositions exist.
