Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624442, here are decompositions:

59 + 8624383 = 8624442
89 + 8624353 = 8624442
131 + 8624311 = 8624442
191 + 8624251 = 8624442
193 + 8624249 = 8624442
199 + 8624243 = 8624442
241 + 8624201 = 8624442
251 + 8624191 = 8624442

Showing the first eight; more decompositions exist.
