Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31555054, here are decompositions:

23 + 31555031 = 31555054
107 + 31554947 = 31555054
191 + 31554863 = 31555054
257 + 31554797 = 31555054
263 + 31554791 = 31555054
383 + 31554671 = 31555054
653 + 31554401 = 31555054
911 + 31554143 = 31555054

Showing the first eight; more decompositions exist.
