Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554926, here are decompositions:

37 + 31554889 = 31554926
43 + 31554883 = 31554926
97 + 31554829 = 31554926
103 + 31554823 = 31554926
307 + 31554619 = 31554926
313 + 31554613 = 31554926
409 + 31554517 = 31554926
433 + 31554493 = 31554926

Showing the first eight; more decompositions exist.
