Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489654, here are decompositions:

3 + 31489651 = 31489654
41 + 31489613 = 31489654
83 + 31489571 = 31489654
113 + 31489541 = 31489654
191 + 31489463 = 31489654
227 + 31489427 = 31489654
263 + 31489391 = 31489654
461 + 31489193 = 31489654

Showing the first eight; more decompositions exist.
