Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540588, here are decompositions:

59 + 31540529 = 31540588
89 + 31540499 = 31540588
347 + 31540241 = 31540588
479 + 31540109 = 31540588
557 + 31540031 = 31540588
617 + 31539971 = 31540588
881 + 31539707 = 31540588
929 + 31539659 = 31540588

Showing the first eight; more decompositions exist.
