Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621542, here are decompositions:

89 + 8621453 = 8621542
113 + 8621429 = 8621542
131 + 8621411 = 8621542
233 + 8621309 = 8621542
353 + 8621189 = 8621542
359 + 8621183 = 8621542
389 + 8621153 = 8621542
491 + 8621051 = 8621542

Showing the first eight; more decompositions exist.
