Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542104, here are decompositions:

37 + 31542067 = 31542104
67 + 31542037 = 31542104
73 + 31542031 = 31542104
103 + 31542001 = 31542104
127 + 31541977 = 31542104
211 + 31541893 = 31542104
277 + 31541827 = 31542104
367 + 31541737 = 31542104

Showing the first eight; more decompositions exist.
