Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537198, here are decompositions:

47 + 31537151 = 31537198
71 + 31537127 = 31537198
101 + 31537097 = 31537198
149 + 31537049 = 31537198
197 + 31537001 = 31537198
239 + 31536959 = 31537198
281 + 31536917 = 31537198
467 + 31536731 = 31537198

Showing the first eight; more decompositions exist.
