Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005854, here are decompositions:

103 + 1005751 = 1005854
193 + 1005661 = 1005854
211 + 1005643 = 1005854
313 + 1005541 = 1005854
373 + 1005481 = 1005854
397 + 1005457 = 1005854
463 + 1005391 = 1005854
523 + 1005331 = 1005854

Showing the first eight; more decompositions exist.
