Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454762, here are decompositions:

61 + 31454701 = 31454762
109 + 31454653 = 31454762
331 + 31454431 = 31454762
373 + 31454389 = 31454762
379 + 31454383 = 31454762
499 + 31454263 = 31454762
541 + 31454221 = 31454762
571 + 31454191 = 31454762

Showing the first eight; more decompositions exist.
