Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498256, here are decompositions:

3 + 31498253 = 31498256
43 + 31498213 = 31498256
67 + 31498189 = 31498256
277 + 31497979 = 31498256
373 + 31497883 = 31498256
397 + 31497859 = 31498256
499 + 31497757 = 31498256
577 + 31497679 = 31498256

Showing the first eight; more decompositions exist.
