Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31560760, here are decompositions:

3 + 31560757 = 31560760
29 + 31560731 = 31560760
41 + 31560719 = 31560760
47 + 31560713 = 31560760
71 + 31560689 = 31560760
83 + 31560677 = 31560760
113 + 31560647 = 31560760
131 + 31560629 = 31560760

Showing the first eight; more decompositions exist.
