Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513060, here are decompositions:

3 + 31513057 = 31513060
11 + 31513049 = 31513060
23 + 31513037 = 31513060
53 + 31513007 = 31513060
101 + 31512959 = 31513060
113 + 31512947 = 31513060
167 + 31512893 = 31513060
191 + 31512869 = 31513060

Showing the first eight; more decompositions exist.
