Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537194, here are decompositions:

41 + 31537153 = 31537194
43 + 31537151 = 31537194
47 + 31537147 = 31537194
61 + 31537133 = 31537194
67 + 31537127 = 31537194
97 + 31537097 = 31537194
107 + 31537087 = 31537194
151 + 31537043 = 31537194

Showing the first eight; more decompositions exist.
