Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562924, here are decompositions:

7 + 31562917 = 31562924
13 + 31562911 = 31562924
97 + 31562827 = 31562924
157 + 31562767 = 31562924
241 + 31562683 = 31562924
307 + 31562617 = 31562924
313 + 31562611 = 31562924
331 + 31562593 = 31562924

Showing the first eight; more decompositions exist.
