Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495634, here are decompositions:

31 + 31495603 = 31495634
43 + 31495591 = 31495634
211 + 31495423 = 31495634
277 + 31495357 = 31495634
283 + 31495351 = 31495634
421 + 31495213 = 31495634
463 + 31495171 = 31495634
487 + 31495147 = 31495634

Showing the first eight; more decompositions exist.
