Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607432, here are decompositions:

139 + 31607293 = 31607432
151 + 31607281 = 31607432
331 + 31607101 = 31607432
691 + 31606741 = 31607432
751 + 31606681 = 31607432
853 + 31606579 = 31607432
1009 + 31606423 = 31607432
1021 + 31606411 = 31607432

Showing the first eight; more decompositions exist.
