Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100814, here are decompositions:

3 + 100811 = 100814
13 + 100801 = 100814
67 + 100747 = 100814
73 + 100741 = 100814
193 + 100621 = 100814
223 + 100591 = 100814
277 + 100537 = 100814
313 + 100501 = 100814

Showing the first eight; more decompositions exist.
