Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448726, here are decompositions:

7 + 31448719 = 31448726
13 + 31448713 = 31448726
19 + 31448707 = 31448726
79 + 31448647 = 31448726
139 + 31448587 = 31448726
193 + 31448533 = 31448726
277 + 31448449 = 31448726
313 + 31448413 = 31448726

Showing the first eight; more decompositions exist.
