Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7072, here are decompositions:

3 + 7069 = 7072
29 + 7043 = 7072
53 + 7019 = 7072
59 + 7013 = 7072
71 + 7001 = 7072
89 + 6983 = 7072
101 + 6971 = 7072
113 + 6959 = 7072

Showing the first eight; more decompositions exist.
