Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555696, here are decompositions:

89 + 31555607 = 31555696
257 + 31555439 = 31555696
383 + 31555313 = 31555696
443 + 31555253 = 31555696
467 + 31555229 = 31555696
509 + 31555187 = 31555696
563 + 31555133 = 31555696
587 + 31555109 = 31555696

Showing the first eight; more decompositions exist.
