Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477036, here are decompositions:

89 + 31476947 = 31477036
293 + 31476743 = 31477036
443 + 31476593 = 31477036
449 + 31476587 = 31477036
587 + 31476449 = 31477036
599 + 31476437 = 31477036
653 + 31476383 = 31477036
683 + 31476353 = 31477036

Showing the first eight; more decompositions exist.
