Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458044, here are decompositions:

31 + 31458013 = 31458044
223 + 31457821 = 31458044
307 + 31457737 = 31458044
337 + 31457707 = 31458044
433 + 31457611 = 31458044
487 + 31457557 = 31458044
661 + 31457383 = 31458044
733 + 31457311 = 31458044

Showing the first eight; more decompositions exist.
