Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607054, here are decompositions:

7 + 31607047 = 31607054
97 + 31606957 = 31607054
103 + 31606951 = 31607054
151 + 31606903 = 31607054
313 + 31606741 = 31607054
373 + 31606681 = 31607054
397 + 31606657 = 31607054
631 + 31606423 = 31607054

Showing the first eight; more decompositions exist.
