Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506346, here are decompositions:

83 + 31506263 = 31506346
173 + 31506173 = 31506346
197 + 31506149 = 31506346
227 + 31506119 = 31506346
317 + 31506029 = 31506346
353 + 31505993 = 31506346
419 + 31505927 = 31506346
503 + 31505843 = 31506346

Showing the first eight; more decompositions exist.
