Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504694, here are decompositions:

3 + 31504691 = 31504694
43 + 31504651 = 31504694
103 + 31504591 = 31504694
127 + 31504567 = 31504694
241 + 31504453 = 31504694
307 + 31504387 = 31504694
337 + 31504357 = 31504694
367 + 31504327 = 31504694

Showing the first eight; more decompositions exist.
