Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501492, here are decompositions:

59 + 31501433 = 31501492
83 + 31501409 = 31501492
89 + 31501403 = 31501492
131 + 31501361 = 31501492
179 + 31501313 = 31501492
263 + 31501229 = 31501492
293 + 31501199 = 31501492
401 + 31501091 = 31501492

Showing the first eight; more decompositions exist.
