Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496012, here are decompositions:

193 + 31495819 = 31496012
211 + 31495801 = 31496012
271 + 31495741 = 31496012
283 + 31495729 = 31496012
349 + 31495663 = 31496012
409 + 31495603 = 31496012
421 + 31495591 = 31496012
661 + 31495351 = 31496012

Showing the first eight; more decompositions exist.
