Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537206, here are decompositions:

5 + 31537201 = 31537206
53 + 31537153 = 31537206
59 + 31537147 = 31537206
73 + 31537133 = 31537206
79 + 31537127 = 31537206
109 + 31537097 = 31537206
157 + 31537049 = 31537206
163 + 31537043 = 31537206

Showing the first eight; more decompositions exist.
