Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580060, here are decompositions:

3 + 31580057 = 31580060
7 + 31580053 = 31580060
13 + 31580047 = 31580060
151 + 31579909 = 31580060
223 + 31579837 = 31580060
229 + 31579831 = 31580060
241 + 31579819 = 31580060
313 + 31579747 = 31580060

Showing the first eight; more decompositions exist.
