Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506376, here are decompositions:

3 + 31506373 = 31506376
17 + 31506359 = 31506376
23 + 31506353 = 31506376
113 + 31506263 = 31506376
227 + 31506149 = 31506376
257 + 31506119 = 31506376
347 + 31506029 = 31506376
383 + 31505993 = 31506376

Showing the first eight; more decompositions exist.
