Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461856, here are decompositions:

5 + 31461851 = 31461856
113 + 31461743 = 31461856
443 + 31461413 = 31461856
563 + 31461293 = 31461856
677 + 31461179 = 31461856
683 + 31461173 = 31461856
743 + 31461113 = 31461856
809 + 31461047 = 31461856

Showing the first eight; more decompositions exist.
