Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541336, here are decompositions:

67 + 31541269 = 31541336
103 + 31541233 = 31541336
157 + 31541179 = 31541336
163 + 31541173 = 31541336
223 + 31541113 = 31541336
397 + 31540939 = 31541336
499 + 31540837 = 31541336
523 + 31540813 = 31541336

Showing the first eight; more decompositions exist.
