Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554134, here are decompositions:

13 + 31554121 = 31554134
61 + 31554073 = 31554134
151 + 31553983 = 31554134
331 + 31553803 = 31554134
373 + 31553761 = 31554134
463 + 31553671 = 31554134
607 + 31553527 = 31554134
631 + 31553503 = 31554134

Showing the first eight; more decompositions exist.
