Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541204, here are decompositions:

31 + 31541173 = 31541204
43 + 31541161 = 31541204
103 + 31541101 = 31541204
157 + 31541047 = 31541204
283 + 31540921 = 31541204
337 + 31540867 = 31541204
367 + 31540837 = 31541204
421 + 31540783 = 31541204

Showing the first eight; more decompositions exist.
