Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506334, here are decompositions:

3 + 31506331 = 31506334
23 + 31506311 = 31506334
71 + 31506263 = 31506334
263 + 31506071 = 31506334
491 + 31505843 = 31506334
521 + 31505813 = 31506334
593 + 31505741 = 31506334
641 + 31505693 = 31506334

Showing the first eight; more decompositions exist.
