Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474200, here are decompositions:

29 + 31474171 = 31474200
59 + 31474141 = 31474200
71 + 31474129 = 31474200
89 + 31474111 = 31474200
127 + 31474073 = 31474200
139 + 31474061 = 31474200
157 + 31474043 = 31474200
167 + 31474033 = 31474200

Showing the first eight; more decompositions exist.
