Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72698, here are decompositions:

19 + 72679 = 72698
37 + 72661 = 72698
139 + 72559 = 72698
151 + 72547 = 72698
229 + 72469 = 72698
277 + 72421 = 72698
331 + 72367 = 72698
421 + 72277 = 72698

Showing the first eight; more decompositions exist.
