Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629542, here are decompositions:

59 + 8629483 = 8629542
101 + 8629441 = 8629542
109 + 8629433 = 8629542
113 + 8629429 = 8629542
193 + 8629349 = 8629542
199 + 8629343 = 8629542
263 + 8629279 = 8629542
349 + 8629193 = 8629542

Showing the first eight; more decompositions exist.
