Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504748, here are decompositions:

97 + 31504651 = 31504748
157 + 31504591 = 31504748
181 + 31504567 = 31504748
397 + 31504351 = 31504748
421 + 31504327 = 31504748
547 + 31504201 = 31504748
619 + 31504129 = 31504748
661 + 31504087 = 31504748

Showing the first eight; more decompositions exist.
