Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540010, here are decompositions:

3 + 31540007 = 31540010
43 + 31539967 = 31540010
79 + 31539931 = 31540010
109 + 31539901 = 31540010
193 + 31539817 = 31540010
283 + 31539727 = 31540010
349 + 31539661 = 31540010
367 + 31539643 = 31540010

Showing the first eight; more decompositions exist.
