Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448846, here are decompositions:

7 + 31448839 = 31448846
43 + 31448803 = 31448846
127 + 31448719 = 31448846
139 + 31448707 = 31448846
199 + 31448647 = 31448846
313 + 31448533 = 31448846
367 + 31448479 = 31448846
397 + 31448449 = 31448846

Showing the first eight; more decompositions exist.
