Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72626, here are decompositions:

3 + 72623 = 72626
13 + 72613 = 72626
67 + 72559 = 72626
79 + 72547 = 72626
157 + 72469 = 72626
313 + 72313 = 72626
349 + 72277 = 72626
373 + 72253 = 72626

Showing the first eight; more decompositions exist.
