Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72154, here are decompositions:

53 + 72101 = 72154
101 + 72053 = 72154
107 + 72047 = 72154
167 + 71987 = 72154
191 + 71963 = 72154
293 + 71861 = 72154
311 + 71843 = 72154
317 + 71837 = 72154

Showing the first eight; more decompositions exist.
