Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524116, here are decompositions:

67 + 31524049 = 31524116
73 + 31524043 = 31524116
103 + 31524013 = 31524116
163 + 31523953 = 31524116
199 + 31523917 = 31524116
277 + 31523839 = 31524116
313 + 31523803 = 31524116
367 + 31523749 = 31524116

Showing the first eight; more decompositions exist.
