Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501194, here are decompositions:

103 + 31501091 = 31501194
113 + 31501081 = 31501194
157 + 31501037 = 31501194
227 + 31500967 = 31501194
271 + 31500923 = 31501194
331 + 31500863 = 31501194
397 + 31500797 = 31501194
401 + 31500793 = 31501194

Showing the first eight; more decompositions exist.
