Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484346, here are decompositions:

7 + 31484339 = 31484346
29 + 31484317 = 31484346
43 + 31484303 = 31484346
79 + 31484267 = 31484346
107 + 31484239 = 31484346
109 + 31484237 = 31484346
137 + 31484209 = 31484346
139 + 31484207 = 31484346

Showing the first eight; more decompositions exist.
