Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632478, here are decompositions:

67 + 8632411 = 8632478
79 + 8632399 = 8632478
97 + 8632381 = 8632478
181 + 8632297 = 8632478
199 + 8632279 = 8632478
241 + 8632237 = 8632478
397 + 8632081 = 8632478
409 + 8632069 = 8632478

Showing the first eight; more decompositions exist.
