Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631400, here are decompositions:

59 + 8631341 = 8631400
131 + 8631269 = 8631400
149 + 8631251 = 8631400
233 + 8631167 = 8631400
317 + 8631083 = 8631400
359 + 8631041 = 8631400
383 + 8631017 = 8631400
389 + 8631011 = 8631400

Showing the first eight; more decompositions exist.
