Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506262, here are decompositions:

89 + 31506173 = 31506262
113 + 31506149 = 31506262
191 + 31506071 = 31506262
233 + 31506029 = 31506262
269 + 31505993 = 31506262
353 + 31505909 = 31506262
419 + 31505843 = 31506262
449 + 31505813 = 31506262

Showing the first eight; more decompositions exist.
