Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102446, here are decompositions:

13 + 102433 = 102446
37 + 102409 = 102446
79 + 102367 = 102446
109 + 102337 = 102446
193 + 102253 = 102446
229 + 102217 = 102446
307 + 102139 = 102446
367 + 102079 = 102446

Showing the first eight; more decompositions exist.
