Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574632, here are decompositions:

101 + 31574531 = 31574632
179 + 31574453 = 31574632
263 + 31574369 = 31574632
269 + 31574363 = 31574632
431 + 31574201 = 31574632
701 + 31573931 = 31574632
773 + 31573859 = 31574632
809 + 31573823 = 31574632

Showing the first eight; more decompositions exist.
