Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554958, here are decompositions:

11 + 31554947 = 31554958
59 + 31554899 = 31554958
107 + 31554851 = 31554958
167 + 31554791 = 31554958
317 + 31554641 = 31554958
389 + 31554569 = 31554958
419 + 31554539 = 31554958
431 + 31554527 = 31554958

Showing the first eight; more decompositions exist.
