Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541502, here are decompositions:

19 + 31541483 = 31541502
53 + 31541449 = 31541502
73 + 31541429 = 31541502
101 + 31541401 = 31541502
103 + 31541399 = 31541502
233 + 31541269 = 31541502
269 + 31541233 = 31541502
373 + 31541129 = 31541502

Showing the first eight; more decompositions exist.
