Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599974, here are decompositions:

61 + 31599913 = 31599974
73 + 31599901 = 31599974
97 + 31599877 = 31599974
103 + 31599871 = 31599974
151 + 31599823 = 31599974
163 + 31599811 = 31599974
193 + 31599781 = 31599974
271 + 31599703 = 31599974

Showing the first eight; more decompositions exist.
