Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465192, here are decompositions:

131 + 31465061 = 31465192
251 + 31464941 = 31465192
383 + 31464809 = 31465192
461 + 31464731 = 31465192
491 + 31464701 = 31465192
683 + 31464509 = 31465192
911 + 31464281 = 31465192
1049 + 31464143 = 31465192

Showing the first eight; more decompositions exist.
