Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576292, here are decompositions:

3 + 31576289 = 31576292
31 + 31576261 = 31576292
61 + 31576231 = 31576292
73 + 31576219 = 31576292
283 + 31576009 = 31576292
463 + 31575829 = 31576292
499 + 31575793 = 31576292
523 + 31575769 = 31576292

Showing the first eight; more decompositions exist.
