Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31600132, here are decompositions:

29 + 31600103 = 31600132
71 + 31600061 = 31600132
89 + 31600043 = 31600132
131 + 31600001 = 31600132
173 + 31599959 = 31600132
191 + 31599941 = 31600132
359 + 31599773 = 31600132
449 + 31599683 = 31600132

Showing the first eight; more decompositions exist.
