Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610054, here are decompositions:

31 + 31610023 = 31610054
43 + 31610011 = 31610054
61 + 31609993 = 31610054
97 + 31609957 = 31610054
193 + 31609861 = 31610054
241 + 31609813 = 31610054
277 + 31609777 = 31610054
313 + 31609741 = 31610054

Showing the first eight; more decompositions exist.
