Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156390, here are decompositions:

19 + 156371 = 156390
29 + 156361 = 156390
37 + 156353 = 156390
43 + 156347 = 156390
61 + 156329 = 156390
71 + 156319 = 156390
83 + 156307 = 156390
131 + 156259 = 156390

Showing the first eight; more decompositions exist.
