Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625902, here are decompositions:

53 + 31625849 = 31625902
59 + 31625843 = 31625902
83 + 31625819 = 31625902
149 + 31625753 = 31625902
179 + 31625723 = 31625902
251 + 31625651 = 31625902
449 + 31625453 = 31625902
491 + 31625411 = 31625902

Showing the first eight; more decompositions exist.
