Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454830, here are decompositions:

3 + 31454827 = 31454830
47 + 31454783 = 31454830
89 + 31454741 = 31454830
149 + 31454681 = 31454830
179 + 31454651 = 31454830
317 + 31454513 = 31454830
347 + 31454483 = 31454830
389 + 31454441 = 31454830

Showing the first eight; more decompositions exist.
