Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501754, here are decompositions:

3 + 31501751 = 31501754
13 + 31501741 = 31501754
223 + 31501531 = 31501754
307 + 31501447 = 31501754
367 + 31501387 = 31501754
421 + 31501333 = 31501754
433 + 31501321 = 31501754
523 + 31501231 = 31501754

Showing the first eight; more decompositions exist.
