Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156078, here are decompositions:

7 + 156071 = 156078
17 + 156061 = 156078
19 + 156059 = 156078
37 + 156041 = 156078
59 + 156019 = 156078
67 + 156011 = 156078
71 + 156007 = 156078
157 + 155921 = 156078

Showing the first eight; more decompositions exist.
