Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484238, here are decompositions:

29 + 31484209 = 31484238
31 + 31484207 = 31484238
59 + 31484179 = 31484238
61 + 31484177 = 31484238
109 + 31484129 = 31484238
157 + 31484081 = 31484238
167 + 31484071 = 31484238
179 + 31484059 = 31484238

Showing the first eight; more decompositions exist.
