Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462070, here are decompositions:

67 + 31462003 = 31462070
109 + 31461961 = 31462070
127 + 31461943 = 31462070
151 + 31461919 = 31462070
229 + 31461841 = 31462070
307 + 31461763 = 31462070
373 + 31461697 = 31462070
397 + 31461673 = 31462070

Showing the first eight; more decompositions exist.
