Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501744, here are decompositions:

3 + 31501741 = 31501744
17 + 31501727 = 31501744
23 + 31501721 = 31501744
83 + 31501661 = 31501744
311 + 31501433 = 31501744
317 + 31501427 = 31501744
383 + 31501361 = 31501744
431 + 31501313 = 31501744

Showing the first eight; more decompositions exist.
