Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463138, here are decompositions:

61 + 31463077 = 31463138
229 + 31462909 = 31463138
241 + 31462897 = 31463138
307 + 31462831 = 31463138
331 + 31462807 = 31463138
367 + 31462771 = 31463138
379 + 31462759 = 31463138
409 + 31462729 = 31463138

Showing the first eight; more decompositions exist.
