Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452648, here are decompositions:

41 + 31452607 = 31452648
61 + 31452587 = 31452648
109 + 31452539 = 31452648
127 + 31452521 = 31452648
131 + 31452517 = 31452648
151 + 31452497 = 31452648
167 + 31452481 = 31452648
197 + 31452451 = 31452648

Showing the first eight; more decompositions exist.
