Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462010, here are decompositions:

3 + 31462007 = 31462010
7 + 31462003 = 31462010
31 + 31461979 = 31462010
61 + 31461949 = 31462010
67 + 31461943 = 31462010
193 + 31461817 = 31462010
199 + 31461811 = 31462010
313 + 31461697 = 31462010

Showing the first eight; more decompositions exist.
