Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554802, here are decompositions:

5 + 31554797 = 31554802
11 + 31554791 = 31554802
53 + 31554749 = 31554802
131 + 31554671 = 31554802
233 + 31554569 = 31554802
263 + 31554539 = 31554802
353 + 31554449 = 31554802
401 + 31554401 = 31554802

Showing the first eight; more decompositions exist.
