Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504700, here are decompositions:

109 + 31504591 = 31504700
127 + 31504573 = 31504700
313 + 31504387 = 31504700
349 + 31504351 = 31504700
373 + 31504327 = 31504700
397 + 31504303 = 31504700
499 + 31504201 = 31504700
571 + 31504129 = 31504700

Showing the first eight; more decompositions exist.
