Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484236, here are decompositions:

29 + 31484207 = 31484236
59 + 31484177 = 31484236
107 + 31484129 = 31484236
167 + 31484069 = 31484236
257 + 31483979 = 31484236
317 + 31483919 = 31484236
347 + 31483889 = 31484236
353 + 31483883 = 31484236

Showing the first eight; more decompositions exist.
