Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469940, here are decompositions:

61 + 469879 = 469940
139 + 469801 = 469940
193 + 469747 = 469940
223 + 469717 = 469940
283 + 469657 = 469940
313 + 469627 = 469940
379 + 469561 = 469940
397 + 469543 = 469940

Showing the first eight; more decompositions exist.
