Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465652, here are decompositions:

3 + 31465649 = 31465652
73 + 31465579 = 31465652
193 + 31465459 = 31465652
331 + 31465321 = 31465652
409 + 31465243 = 31465652
499 + 31465153 = 31465652
523 + 31465129 = 31465652
541 + 31465111 = 31465652

Showing the first eight; more decompositions exist.
