Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542944, here are decompositions:

3 + 31542941 = 31542944
7 + 31542937 = 31542944
67 + 31542877 = 31542944
157 + 31542787 = 31542944
241 + 31542703 = 31542944
313 + 31542631 = 31542944
331 + 31542613 = 31542944
397 + 31542547 = 31542944

Showing the first eight; more decompositions exist.
