Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72506, here are decompositions:

3 + 72503 = 72506
13 + 72493 = 72506
37 + 72469 = 72506
127 + 72379 = 72506
139 + 72367 = 72506
193 + 72313 = 72506
199 + 72307 = 72506
229 + 72277 = 72506

Showing the first eight; more decompositions exist.
