Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448998, here are decompositions:

11 + 31448987 = 31448998
89 + 31448909 = 31448998
101 + 31448897 = 31448998
107 + 31448891 = 31448998
257 + 31448741 = 31448998
281 + 31448717 = 31448998
359 + 31448639 = 31448998
419 + 31448579 = 31448998

Showing the first eight; more decompositions exist.
