Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501876, here are decompositions:

53 + 31501823 = 31501876
149 + 31501727 = 31501876
257 + 31501619 = 31501876
293 + 31501583 = 31501876
353 + 31501523 = 31501876
443 + 31501433 = 31501876
449 + 31501427 = 31501876
467 + 31501409 = 31501876

Showing the first eight; more decompositions exist.
