Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496754, here are decompositions:

13 + 31496741 = 31496754
61 + 31496693 = 31496754
83 + 31496671 = 31496754
167 + 31496587 = 31496754
181 + 31496573 = 31496754
313 + 31496441 = 31496754
337 + 31496417 = 31496754
383 + 31496371 = 31496754

Showing the first eight; more decompositions exist.
