Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619692, here are decompositions:

23 + 31619669 = 31619692
89 + 31619603 = 31619692
131 + 31619561 = 31619692
149 + 31619543 = 31619692
173 + 31619519 = 31619692
191 + 31619501 = 31619692
233 + 31619459 = 31619692
431 + 31619261 = 31619692

Showing the first eight; more decompositions exist.
