Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613060, here are decompositions:

7 + 31613053 = 31613060
79 + 31612981 = 31613060
109 + 31612951 = 31613060
229 + 31612831 = 31613060
307 + 31612753 = 31613060
313 + 31612747 = 31613060
331 + 31612729 = 31613060
397 + 31612663 = 31613060

Showing the first eight; more decompositions exist.
