Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520954, here are decompositions:

37 + 31520917 = 31520954
43 + 31520911 = 31520954
97 + 31520857 = 31520954
103 + 31520851 = 31520954
193 + 31520761 = 31520954
337 + 31520617 = 31520954
373 + 31520581 = 31520954
457 + 31520497 = 31520954

Showing the first eight; more decompositions exist.
