Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449446, here are decompositions:

37 + 31449409 = 31449446
43 + 31449403 = 31449446
73 + 31449373 = 31449446
157 + 31449289 = 31449446
199 + 31449247 = 31449446
283 + 31449163 = 31449446
409 + 31449037 = 31449446
547 + 31448899 = 31449446

Showing the first eight; more decompositions exist.
