Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460588, here are decompositions:

7 + 31460581 = 31460588
37 + 31460551 = 31460588
79 + 31460509 = 31460588
97 + 31460491 = 31460588
157 + 31460431 = 31460588
241 + 31460347 = 31460588
307 + 31460281 = 31460588
421 + 31460167 = 31460588

Showing the first eight; more decompositions exist.
