Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454606, here are decompositions:

19 + 31454587 = 31454606
109 + 31454497 = 31454606
223 + 31454383 = 31454606
229 + 31454377 = 31454606
409 + 31454197 = 31454606
457 + 31454149 = 31454606
523 + 31454083 = 31454606
613 + 31453993 = 31454606

Showing the first eight; more decompositions exist.
