Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540904, here are decompositions:

37 + 31540867 = 31540904
67 + 31540837 = 31540904
181 + 31540723 = 31540904
211 + 31540693 = 31540904
331 + 31540573 = 31540904
433 + 31540471 = 31540904
463 + 31540441 = 31540904
487 + 31540417 = 31540904

Showing the first eight; more decompositions exist.
