Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504166, here are decompositions:

37 + 31504129 = 31504166
79 + 31504087 = 31504166
193 + 31503973 = 31504166
283 + 31503883 = 31504166
313 + 31503853 = 31504166
367 + 31503799 = 31504166
433 + 31503733 = 31504166
439 + 31503727 = 31504166

Showing the first eight; more decompositions exist.
