Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591060, here are decompositions:

23 + 31591037 = 31591060
29 + 31591031 = 31591060
47 + 31591013 = 31591060
101 + 31590959 = 31591060
131 + 31590929 = 31591060
167 + 31590893 = 31591060
173 + 31590887 = 31591060
227 + 31590833 = 31591060

Showing the first eight; more decompositions exist.
