Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454802, here are decompositions:

19 + 31454783 = 31454802
61 + 31454741 = 31454802
101 + 31454701 = 31454802
149 + 31454653 = 31454802
151 + 31454651 = 31454802
419 + 31454383 = 31454802
601 + 31454201 = 31454802
641 + 31454161 = 31454802

Showing the first eight; more decompositions exist.
