Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501192, here are decompositions:

101 + 31501091 = 31501192
131 + 31501061 = 31501192
251 + 31500941 = 31501192
269 + 31500923 = 31501192
293 + 31500899 = 31501192
383 + 31500809 = 31501192
419 + 31500773 = 31501192
479 + 31500713 = 31501192

Showing the first eight; more decompositions exist.
