Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535756, here are decompositions:

3 + 31535753 = 31535756
163 + 31535593 = 31535756
337 + 31535419 = 31535756
379 + 31535377 = 31535756
523 + 31535233 = 31535756
613 + 31535143 = 31535756
643 + 31535113 = 31535756
673 + 31535083 = 31535756

Showing the first eight; more decompositions exist.
