Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72054, here are decompositions:

7 + 72047 = 72054
11 + 72043 = 72054
23 + 72031 = 72054
61 + 71993 = 72054
67 + 71987 = 72054
71 + 71983 = 72054
83 + 71971 = 72054
107 + 71947 = 72054

Showing the first eight; more decompositions exist.
