Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502038, here are decompositions:

59 + 31501979 = 31502038
101 + 31501937 = 31502038
131 + 31501907 = 31502038
257 + 31501781 = 31502038
311 + 31501727 = 31502038
317 + 31501721 = 31502038
419 + 31501619 = 31502038
677 + 31501361 = 31502038

Showing the first eight; more decompositions exist.
