Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448888, here are decompositions:

67 + 31448821 = 31448888
181 + 31448707 = 31448888
241 + 31448647 = 31448888
307 + 31448581 = 31448888
337 + 31448551 = 31448888
409 + 31448479 = 31448888
439 + 31448449 = 31448888
607 + 31448281 = 31448888

Showing the first eight; more decompositions exist.
