Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554230, here are decompositions:

31 + 31554199 = 31554230
67 + 31554163 = 31554230
109 + 31554121 = 31554230
157 + 31554073 = 31554230
397 + 31553833 = 31554230
523 + 31553707 = 31554230
571 + 31553659 = 31554230
613 + 31553617 = 31554230

Showing the first eight; more decompositions exist.
