Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480852, here are decompositions:

3 + 31480849 = 31480852
23 + 31480829 = 31480852
59 + 31480793 = 31480852
83 + 31480769 = 31480852
89 + 31480763 = 31480852
419 + 31480433 = 31480852
461 + 31480391 = 31480852
479 + 31480373 = 31480852

Showing the first eight; more decompositions exist.
