Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541236, here are decompositions:

3 + 31541233 = 31541236
107 + 31541129 = 31541236
197 + 31541039 = 31541236
257 + 31540979 = 31541236
449 + 31540787 = 31541236
509 + 31540727 = 31541236
557 + 31540679 = 31541236
593 + 31540643 = 31541236

Showing the first eight; more decompositions exist.
