Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477300, here are decompositions:

11 + 31477289 = 31477300
137 + 31477163 = 31477300
233 + 31477067 = 31477300
353 + 31476947 = 31477300
383 + 31476917 = 31477300
419 + 31476881 = 31477300
479 + 31476821 = 31477300
557 + 31476743 = 31477300

Showing the first eight; more decompositions exist.
