Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72338, here are decompositions:

31 + 72307 = 72338
61 + 72277 = 72338
67 + 72271 = 72338
109 + 72229 = 72338
127 + 72211 = 72338
199 + 72139 = 72338
229 + 72109 = 72338
307 + 72031 = 72338

Showing the first eight; more decompositions exist.
