Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540604, here are decompositions:

31 + 31540573 = 31540604
103 + 31540501 = 31540604
163 + 31540441 = 31540604
241 + 31540363 = 31540604
307 + 31540297 = 31540604
397 + 31540207 = 31540604
457 + 31540147 = 31540604
541 + 31540063 = 31540604

Showing the first eight; more decompositions exist.
