Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624156, here are decompositions:

3 + 8624153 = 8624156
19 + 8624137 = 8624156
97 + 8624059 = 8624156
139 + 8624017 = 8624156
193 + 8623963 = 8624156
313 + 8623843 = 8624156
349 + 8623807 = 8624156
439 + 8623717 = 8624156

Showing the first eight; more decompositions exist.
