Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546946, here are decompositions:

37 + 31546909 = 31546946
103 + 31546843 = 31546946
139 + 31546807 = 31546946
157 + 31546789 = 31546946
229 + 31546717 = 31546946
283 + 31546663 = 31546946
313 + 31546633 = 31546946
349 + 31546597 = 31546946

Showing the first eight; more decompositions exist.
