Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464170, here are decompositions:

103 + 31464067 = 31464170
109 + 31464061 = 31464170
139 + 31464031 = 31464170
211 + 31463959 = 31464170
229 + 31463941 = 31464170
277 + 31463893 = 31464170
313 + 31463857 = 31464170
373 + 31463797 = 31464170

Showing the first eight; more decompositions exist.
