Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477510, here are decompositions:

3 + 31477507 = 31477510
83 + 31477427 = 31477510
131 + 31477379 = 31477510
347 + 31477163 = 31477510
431 + 31477079 = 31477510
443 + 31477067 = 31477510
563 + 31476947 = 31477510
593 + 31476917 = 31477510

Showing the first eight; more decompositions exist.
