Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522742, here are decompositions:

73 + 31522669 = 31522742
79 + 31522663 = 31522742
109 + 31522633 = 31522742
151 + 31522591 = 31522742
193 + 31522549 = 31522742
283 + 31522459 = 31522742
331 + 31522411 = 31522742
379 + 31522363 = 31522742

Showing the first eight; more decompositions exist.
