Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462236, here are decompositions:

19 + 31462217 = 31462236
103 + 31462133 = 31462236
109 + 31462127 = 31462236
167 + 31462069 = 31462236
229 + 31462007 = 31462236
233 + 31462003 = 31462236
257 + 31461979 = 31462236
293 + 31461943 = 31462236

Showing the first eight; more decompositions exist.
